-# Contributing to Nix
-
-Welcome and thank you for your interest in contributing to Nix!
-We appreciate your support.
-
-Reading and following these guidelines will help us make the contribution process easy and effective for everyone involved.
-
-## Report a bug
-
-1. Check on the [GitHub issue tracker](https://github.com/NixOS/nix/issues) if your bug was already reported.
-
-2. If you were not able to find the bug or feature [open a new issue](https://github.com/NixOS/nix/issues/new/choose)
-
-3. The issue templates will guide you in specifying your issue.
-   The more complete the information you provide, the more likely it can be found by others and the more useful it is in the future.
-   Make sure reported bugs can be reproduced easily.
-
-4. Once submitted, do not expect issues to be picked up or solved right away.
-   The only way to ensure this, is to [work on the issue yourself](#making-changes-to-nix).
-
-## Report a security vulnerability
-
-Check out the [security policy](https://github.com/NixOS/nix/security/policy).
-
-## Making changes to Nix
-
-1. Search for related issues that cover what you're going to work on.
-   It could help to mention there that you will work on the issue.
-
-   We strongly recommend first-time contributors not to propose new features but rather fix tightly-scoped problems in order to build trust and a working relationship with maintainers.
-
-   Issues labeled [good first issue](https://github.com/NixOS/nix/labels/good%20first%20issue) should be relatively easy to fix and are likely to get merged quickly.
-   Pull requests addressing issues labeled [idea approved](https://github.com/NixOS/nix/labels/idea%20approved) or [RFC](https://github.com/NixOS/nix/labels/RFC) are especially welcomed by maintainers and will receive prioritised review.
-
-   If you are proficient with C++, addressing one of the [popular issues](https://github.com/NixOS/nix/issues?q=is%3Aissue+is%3Aopen+sort%3Areactions-%2B1-desc) will be highly appreciated by maintainers and Nix users all over the world.
-   For far-reaching changes, please investigate possible blockers and design implications, and coordinate with maintainers before investing too much time in writing code that may not end up getting merged.
-
-   If there is no relevant issue yet and you're not sure whether your change is likely to be accepted, [open an issue](https://github.com/NixOS/nix/issues/new/choose) yourself.
-
-2. Check for [pull requests](https://github.com/NixOS/nix/pulls) that might already cover the contribution you are about to make.
-   There are many open pull requests that might already do what you intend to work on.
-   You can use [labels](https://github.com/NixOS/nix/labels) to filter for relevant topics.
-
-3. Check the [Nix reference manual](https://nix.dev/manual/nix/development/development/building.html) for information on building Nix and running its tests.
-
-   For contributions to the command line interface, please check the [CLI guidelines](https://nix.dev/manual/nix/development/development/cli-guideline.html).
-
-4. Make your change!
-
-5. [Create a pull request](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/proposing-changes-to-your-work-with-pull-requests/creating-a-pull-request) for your changes.
-   * Clearly explain the problem that you're solving.
-
-     Link related issues to inform interested parties and future contributors about your change.
-     If your pull request closes one or multiple issues, mention that in the description using `Closes: #<number>`, as it will then happen automatically when your change is merged.
-   * Credit original authors when you're reusing or building on their work.
-   * Link to relevant changes in other projects, so that others can understand the full context of the change in the future when you or someone else will change or troubleshoot the code.
-     This is especially important when your change is based on work done in other repositories.
-
-     Example:
-     ```
-     This is based on the work of @user in <url>.
-     This solution took inspiration from <url>.
-
-     Co-authored-by: User Name <user@example.com>
-     ```
-
-     When cherry-picking from a different repository, use the `-x` flag, and then amend the commits to turn the hashes into URLs.
-
-   * Make sure to have [a clean history of commits on your branch by using rebase](https://www.digitalocean.com/community/tutorials/how-to-rebase-and-update-a-pull-request).
-   * [Mark the pull request as draft](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/proposing-changes-to-your-work-with-pull-requests/changing-the-stage-of-a-pull-request) if you're not done with the changes.
-
-6. Do not expect your pull request to be reviewed immediately.
-   Nix maintainers follow a [structured process for reviews and design decisions](https://github.com/NixOS/nix/tree/master/maintainers#project-board-protocol), which may or may not prioritise your work.
-
-   Following this checklist will make the process smoother for everyone:
-
-   - [ ] Fixes an [idea approved](https://github.com/NixOS/nix/labels/idea%20approved) issue
-   - [ ] Tests, as appropriate:
-     - Functional tests – [`tests/functional/**.sh`](./tests/functional)
-     - Unit tests – [`src/*/tests`](./src/)
-     - Integration tests – [`tests/nixos/*`](./tests/nixos)
-   - [ ] User documentation in the [manual](./doc/manual/source)
-   - [ ] API documentation in header files
-   - [ ] Code and comments are self-explanatory
-   - [ ] Commit message explains **why** the change was made
-   - [ ] New feature or incompatible change: [add a release note](https://nix.dev/manual/nix/development/development/contributing.html#add-a-release-note)
-
-7. If you need additional feedback or help to getting pull request into shape, ask other contributors using [@mentions](https://docs.github.com/en/get-started/writing-on-github/getting-started-with-writing-and-formatting-on-github/basic-writing-and-formatting-syntax#mentioning-people-and-teams).
-
-## Making changes to the Nix manual
-
-The Nix reference manual is hosted on https://nixos.org/manual/nix.
-The underlying source files are located in [`doc/manual/source`](./doc/manual/source).
-For small changes you can [use GitHub to edit these files](https://docs.github.com/en/repositories/working-with-files/managing-files/editing-files)
-For larger changes see the [Nix reference manual](https://nix.dev/manual/nix/development/development/contributing.html).
-
-## Getting help
-
-Whenever you're stuck or do not know how to proceed, you can always ask for help.
-We invite you to use our [Matrix room](https://matrix.to/#/#nix-dev:nixos.org) to ask questions.

+## Installation
 
-Visit [nix.dev](https://nix.dev) for [installation instructions](https://nix.dev/tutorials/install-nix) and [beginner tutorials](https://nix.dev/tutorials/first-steps).
+On Linux and macOS the easiest way to install Nix is to run the following shell command
+(as a user other than root):
 
-Full reference documentation can be found in the [Nix manual](https://nix.dev/reference/nix-manual).
+```console
+$ curl -L https://nixos.org/nix/install | sh
+```
 
-## Building and developing
+Information on additional installation methods is available on the [Nix download page](https://nixos.org/download.html).
 
-Follow instructions in the Nix reference manual to [set up a development environment and build Nix from source](https://nix.dev/manual/nix/development/development/building.html).

-// the following code matches the current page's URL against the set of redirects.
-//
-// it is written to minimize the latency between page load and redirect.
-// therefore we avoid function calls, copying data, and unnecessary loops.
-// IMPORTANT: we use stateful array operations and their order matters!
-//
-// matching URLs is more involved than it should be:
-//
-// 1. `document.location.pathname` can have an arbitrary prefix.
-//
-// 2. `path_to_root` is set by mdBook. it consists only of `../`s and
-//    determines the depth of `<path>` relative to the prefix:
-//
-//          `document.location.pathname`
-//        |------------------------------|
-//        /<prefix>/<path>/[<file>[.html]][#<anchor>]
-//                  |----|
-//              `path_to_root` has same number of path segments
-//
-//    source: https://phaiax.github.io/mdBook/format/theme/index-hbs.html#data
-//
-// 3. the following paths are equivalent:
-//
-//        /foo/bar/
-//        /foo/bar/index.html

-//    hence first element of `segments` is always empty.
-// 2. last element of splitting `path_to_root` is also always empty.
-// 3. last element of `segments` is the file name.
-//
-// visual example:
-//
-//     '/foo/bar/baz.html'.split('/') -> [ '', 'foo', 'bar', 'baz.html' ]
-//          '../'.split('/')          -> [ '..', '' ]
-//
-// the following operations will then result in
-//
-//     path = 'bar/baz.html'
-//
-segments.splice(0, segments.length - depth);
-const path = segments.join('/');
-
-// anchor starts with the hash character (`#`),
-// but our redirect declarations don't, so we strip it.
-// example:
-//     document.location.hash -> '#foo'
-//     document.location.hash.substring(1) -> 'foo'
-const anchor = document.location.hash.substring(1);
-
-const redirect = redirects[path];
-if (redirect) {

-# Remote Builds
-
-A local Nix installation can forward Nix builds to other machines,
-this allows multiple builds to be performed in parallel.
-
-Remote builds also allow Nix to perform multi-platform builds in a
-semi-transparent way. For example, if you perform a build for a
-`x86_64-darwin` on an `i686-linux` machine, Nix can automatically
-forward the build to a `x86_64-darwin` machine, if one is available.
-
-## Requirements
-
-For a local machine to forward a build to a remote machine, the remote machine must:
-
-- Have Nix installed
-- Be running an SSH server, e.g. `sshd`
-- Be accessible via SSH from the local machine over the network
-- Have the local machine's public SSH key in `/etc/ssh/authorized_keys.d/<username>`
-- Have the username of the SSH user in the `trusted-users` setting in `nix.conf`
-
-## Testing
-
-To test connecting to a remote [Nix instance] (in this case `mac`), run:
-
-```console
-nix store info --store ssh://username@mac
-```
-
-To specify an SSH identity file as part of the remote store URI add a
-query parameter, e.g.
-
-```console
-nix store info --store ssh://username@mac?ssh-key=/home/alice/my-key
-```
-
-Since builds should be non-interactive, the key should not have a
-passphrase. Alternatively, you can load identities ahead of time into
-`ssh-agent` or `gpg-agent`.
-
-In a multi-user installation (default), builds are executed by the Nix
-Daemon. The Nix Daemon cannot prompt for a passphrase via the terminal
-or `ssh-agent`, so the SSH key must not have a passphrase.
-
-In addition, the Nix Daemon's user (typically root) needs to have SSH
-access to the remote builder.
-
-Access can be verified by running `sudo su`, and then validating SSH
-access, e.g. by running `ssh mac`. SSH identity files for root users
-are usually stored in `/root/.ssh/` (Linux) or `/var/root/.ssh` (MacOS).
-
-If you get the error
-
-```console
-bash: nix: command not found
-error: cannot connect to 'mac'
-```
-
-then you need to ensure that the `PATH` of non-interactive login shells
-contains Nix.
-
-The [list of remote build machines](@docroot@/command-ref/conf-file.md#conf-builders) can be specified on the command line or in the Nix configuration file.
-For example, the following command allows you to build a derivation for `x86_64-darwin` on a Linux machine:
-
-```console

-
-After making changes to `nix.conf`, restart the Nix daemon for changes to take effect.
-
-Finally, remote build machines can be configured in a separate configuration
-file included in `builders` via the syntax `@/path/to/file`. For example,
-
-    builders = @/etc/nix/machines
-
-causes the list of machines in `/etc/nix/machines` to be included.

-# Architecture
-
-This chapter describes how Nix works.
-It should help users understand why Nix behaves as it does, and it should help developers understand how to modify Nix and how to write similar tools.
-
-## Overview
-
-Nix consists of [hierarchical layers].

-
-At the top is the [command line interface](../command-ref/index.md) that drives the underlying layers.
-
-The [Nix language](../language/index.md) evaluator transforms Nix expressions into self-contained *build plans*, which are used to derive *build results* from referenced *build inputs*.
-
-The command line interface and Nix expressions are what users deal with most.
-
-> **Note**
->
-> The Nix language itself does not have a notion of *packages* or *configurations*.
-> As far as we are concerned here, the inputs and results of a build plan are just data.
-
-Underlying the command line interface and the Nix language evaluator is the [Nix store](../store/index.md), a mechanism to keep track of build plans, data, and references between them.
-It can also execute build plans to produce new data, which are made available to the operating system as files.
-
-A build plan itself is a series of *build tasks*, together with their build inputs.
-
-> **Important**
-> A build task in Nix is called [store derivation](@docroot@/glossary.md#gloss-store-derivation).
-
-Each build task has a special build input executed as *build instructions* in order to perform the build.
-The result of a build task can be input to another build task.
-
-The following [data flow diagram] shows a build plan for illustration.
-Build inputs used as instructions to a build task are marked accordingly:

-# Name
-
-`nix.conf` - Nix configuration file
-
-# Description
-
-Nix supports a variety of configuration settings, which are read from configuration files or taken as command line flags.
-
-## Configuration file
-
-By default Nix reads settings from the following places, in that order:
-
-1. The system-wide configuration file `sysconfdir/nix/nix.conf` (i.e. `/etc/nix/nix.conf` on most systems), or `$NIX_CONF_DIR/nix.conf` if [`NIX_CONF_DIR`](./env-common.md#env-NIX_CONF_DIR) is set.
-
-   Values loaded in this file are not forwarded to the Nix daemon.
-   The client assumes that the daemon has already loaded them.
-
-1. If [`NIX_USER_CONF_FILES`](./env-common.md#env-NIX_USER_CONF_FILES) is set, then each path separated by `:` will be loaded in reverse order.
-
-   Otherwise it will look for `nix/nix.conf` files in `XDG_CONFIG_DIRS` and [`XDG_CONFIG_HOME`](./env-common.md#env-XDG_CONFIG_HOME).
-   If unset, `XDG_CONFIG_DIRS` defaults to `/etc/xdg`, and `XDG_CONFIG_HOME` defaults to `$HOME/.config` as per [XDG Base Directory Specification](https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html).
-
-1. If [`NIX_CONFIG`](./env-common.md#env-NIX_CONFIG) is set, its contents are treated as the contents of a configuration file.
-
-### File format
-
-Configuration files consist of `name = value` pairs, one per line.
-Comments start with a `#` character.
-
-Example:
-
-```
-keep-outputs = true       # Nice for developers
-keep-derivations = true   # Idem
-```
-
-Other files can be included with a line like `include <path>`, where `<path>` is interpreted relative to the current configuration file.
-A missing file is an error unless `!include` is used instead.
-
-A configuration setting usually overrides any previous value.
-However, for settings that take a list of items, you can prefix the name of the setting by `extra-` to *append* to the previous value.
-
-For instance,
-
-```
-substituters = a b
-extra-substituters = c d
-```
-
-defines the `substituters` setting to be `a b c d`.
-
-Unknown option names are not an error, and are simply ignored with a warning.
-
-## Command line flags
-
-Configuration options can be set on the command line, overriding the values set in the [configuration file](#configuration-file):
-
-- Every configuration setting has corresponding command line flag (e.g. `--max-jobs 16`).
-  Boolean settings do not need an argument, and can be explicitly disabled with the `no-` prefix (e.g. `--keep-failed` and `--no-keep-failed`).
-
-  Unknown option names are invalid flags (unless there is already a flag with that name), and are rejected with an error.
-
-- The flag `--option <name> <value>` is interpreted exactly like a `<name> = <value>` in a setting file.
-
-  Unknown option names are ignored with a warning.
-
-The `extra-` prefix is supported for settings that take a list of items (e.g. `--extra-trusted users alice` or `--option extra-trusted-users alice`).
-
-## Integer settings
-
-Settings that have an integer type support the suffixes `K`, `M`, `G`
-and `T`. These cause the specified value to be multiplied by 2^10,
-2^20, 2^30 and 2^40, respectively. For instance, `--min-free 1M` is
-equivalent to `--min-free 1048576`.

-# Common Environment Variables
-
-Most Nix commands interpret the following environment variables:
-
-- <span id="env-IN_NIX_SHELL">[`IN_NIX_SHELL`](#env-IN_NIX_SHELL)</span>
-
-  Indicator that tells if the current environment was set up by
-  `nix-shell`. It can have the values `pure` or `impure`.
-
-- <span id="env-NIX_PATH">[`NIX_PATH`](#env-NIX_PATH)</span>
-
-  A colon-separated list of search path entries used to resolve [lookup paths](@docroot@/language/constructs/lookup-path.md).
-
-  This environment variable overrides the value of the [`nix-path` configuration setting](@docroot@/command-ref/conf-file.md#conf-nix-path).
-
-  It can be extended using the [`-I` option](@docroot@/command-ref/opt-common.md#opt-I).
-
-  > **Example**
-  >
-  > ```bash
-  > $ export NIX_PATH=`/home/eelco/Dev:nixos-config=/etc/nixos
-  > ```
-
-  If `NIX_PATH` is set to an empty string, resolving search paths will always fail.
-
-  > **Example**
-  >
-  > ```bash
-  > $ NIX_PATH= nix-instantiate --eval '<nixpkgs>'
-  > error: file 'nixpkgs' was not found in the Nix search path (add it using $NIX_PATH or -I)
-  > ```
-
-- <span id="env-NIX_IGNORE_SYMLINK_STORE">[`NIX_IGNORE_SYMLINK_STORE`](#env-NIX_IGNORE_SYMLINK_STORE)</span>
-
-  Normally, the Nix store directory (typically `/nix/store`) is not
-  allowed to contain any symlink components. This is to prevent
-  “impure” builds. Builders sometimes “canonicalise” paths by
-  resolving all symlink components. Thus, builds on different machines
-  (with `/nix/store` resolving to different locations) could yield
-  different results. This is generally not a problem, except when
-  builds are deployed to machines where `/nix/store` resolves
-  differently. If you are sure that you’re not going to do that, you
-  can set `NIX_IGNORE_SYMLINK_STORE` to `1`.
-
-  Note that if you’re symlinking the Nix store so that you can put it
-  on another file system than the root file system, on Linux you’re
-  better off using `bind` mount points, e.g.,
-
-  ```console
-  $ mkdir /nix
-  $ mount -o bind /mnt/otherdisk/nix /nix
-  ```
-
-  Consult the mount 8 manual page for details.
-
-- <span id="env-NIX_STORE_DIR">[`NIX_STORE_DIR`](#env-NIX_STORE_DIR)</span>
-
-  Overrides the location of the Nix store (default `prefix/store`).
-
-- <span id="env-NIX_DATA_DIR">[`NIX_DATA_DIR`](#env-NIX_DATA_DIR)</span>
-
-  Overrides the location of the Nix static data directory (default
-  `prefix/share`).
-
-- <span id="env-NIX_LOG_DIR">[`NIX_LOG_DIR`](#env-NIX_LOG_DIR)</span>
-
-  Overrides the location of the Nix log directory (default
-  `prefix/var/log/nix`).
-
-- <span id="env-NIX_STATE_DIR">[`NIX_STATE_DIR`](#env-NIX_STATE_DIR)</span>
-
-  Overrides the location of the Nix state directory (default
-  `prefix/var/nix`).
-
-- <span id="env-NIX_CONF_DIR">[`NIX_CONF_DIR`](#env-NIX_CONF_DIR)</span>
-
-  Overrides the location of the system Nix configuration directory
-  (default `prefix/etc/nix`).
-
-- <span id="env-NIX_CONFIG">[`NIX_CONFIG`](#env-NIX_CONFIG)</span>
-
-  Applies settings from Nix configuration from the environment.
-  The content is treated as if it was read from a Nix configuration file.
-  Settings are separated by the newline character.
-
-- <span id="env-NIX_USER_CONF_FILES">[`NIX_USER_CONF_FILES`](#env-NIX_USER_CONF_FILES)</span>
-
-  Overrides the location of the Nix user configuration files to load from.
-
-  The default are the locations according to the [XDG Base Directory Specification].
-  See the [XDG Base Directories](#xdg-base-directories) sub-section for details.
-
-  The variable is treated as a list separated by the `:` token.
-
-- <span id="env-TMPDIR">[`TMPDIR`](#env-TMPDIR)</span>
-
-  Use the specified directory to store temporary files. In particular,
-  this includes temporary build directories; these can take up
-  substantial amounts of disk space. The default is `/tmp`.
-
-- <span id="env-NIX_REMOTE">[`NIX_REMOTE`](#env-NIX_REMOTE)</span>
-
-  This variable should be set to `daemon` if you want to use the Nix
-  daemon to execute Nix operations. This is necessary in [multi-user
-  Nix installations](@docroot@/installation/multi-user.md). If the Nix
-  daemon's Unix socket is at some non-standard path, this variable
-  should be set to `unix://path/to/socket`. Otherwise, it should be
-  left unset.
-
-- <span id="env-NIX_SHOW_STATS">[`NIX_SHOW_STATS`](#env-NIX_SHOW_STATS)</span>
-
-  If set to `1`, Nix will print some evaluation statistics, such as
-  the number of values allocated.
-
-- <span id="env-NIX_COUNT_CALLS">[`NIX_COUNT_CALLS`](#env-NIX_COUNT_CALLS)</span>
-
-  If set to `1`, Nix will print how often functions were called during
-  Nix expression evaluation. This is useful for profiling your Nix
-  expressions.
-
-- <span id="env-GC_INITIAL_HEAP_SIZE">[`GC_INITIAL_HEAP_SIZE`](#env-GC_INITIAL_HEAP_SIZE)</span>
-
-  If Nix has been configured to use the Boehm garbage collector, this
-  variable sets the initial size of the heap in bytes. It defaults to
-  384 MiB. Setting it to a low value reduces memory consumption, but
-  will increase runtime due to the overhead of garbage collection.
-
-## XDG Base Directories
-
-Nix follows the [XDG Base Directory Specification].
-

-[New Nix commands](@docroot@/command-ref/new-cli/nix.md) (experimental) conform to the standard by default.
-
-The following environment variables are used to determine locations of various state and configuration files:
-
-- [`XDG_CONFIG_HOME`]{#env-XDG_CONFIG_HOME} (default `~/.config`)
-- [`XDG_STATE_HOME`]{#env-XDG_STATE_HOME} (default `~/.local/state`)

-[`use-xdg-base-directories`]: @docroot@/command-ref/conf-file.md#conf-use-xdg-base-directories
-
-In addition, setting the following environment variables overrides the XDG base directories:
-
-- [`NIX_CONFIG_HOME`]{#env-NIX_CONFIG_HOME} (default `$XDG_CONFIG_HOME/nix`)
-- [`NIX_STATE_HOME`]{#env-NIX_STATE_HOME} (default `$XDG_STATE_HOME/nix`)
-- [`NIX_CACHE_HOME`]{#env-NIX_CACHE_HOME} (default `$XDG_CACHE_HOME/nix`)
-
-When [`use-xdg-base-directories`] is enabled, the configuration directory is:
-
-1. `$NIX_CONFIG_HOME`, if it is defined
-2. Otherwise, `$XDG_CONFIG_HOME/nix`, if `XDG_CONFIG_HOME` is defined
-3. Otherwise, `~/.config/nix`.
-
-Likewise for the state and cache directories.

-## Default Nix expression
-
-The source for the [Nix expressions](@docroot@/glossary.md#gloss-nix-expression) used by [`nix-env`] by default:
-
-- `~/.nix-defexpr`
-- `$XDG_STATE_HOME/nix/defexpr` if [`use-xdg-base-directories`] is set to `true`.
-
-It is loaded as follows:
-
-- If the default expression is a file, it is loaded as a Nix expression.
-- If the default expression is a directory containing a `default.nix` file, that `default.nix` file is loaded as a Nix expression.
-- If the default expression is a directory without a `default.nix` file, then its contents (both files and subdirectories) are loaded as Nix expressions.
-  The expressions are combined into a single attribute set, each expression under an attribute with the same name as the original file or subdirectory.
-  Subdirectories without a `default.nix` file are traversed recursively in search of more Nix expressions, but the names of these intermediate directories are not added to the attribute paths of the default Nix expression.
-
-Then, the resulting expression is interpreted like this:
-
-- If the expression is an attribute set, it is used as the default Nix expression.
-- If the expression is a function, an empty set is passed as argument and the return value is used as the default Nix expression.
-
-> **Example**
->
-> If the default expression contains two files, `foo.nix` and `bar.nix`, then the default Nix expression will be equivalent to
->
-> ```nix
-> {
->   foo = import ~/.nix-defexpr/foo.nix;
->   bar = import ~/.nix-defexpr/bar.nix;
-> }
-> ```
-
-The file [`manifest.nix`](@docroot@/command-ref/files/manifest.nix.md) is always ignored.
-
-The command [`nix-channel`] places a symlink to the current user's [channels] in this directory, the [user channel link](#user-channel-link).
-This makes all subscribed channels available as attributes in the default expression.
-
-## User channel link

-A symlink that ensures that [`nix-env`] can find the current user's [channels]:
-
-- `~/.nix-defexpr/channels`
-- `$XDG_STATE_HOME/defexpr/channels` if [`use-xdg-base-directories`] is set to `true`.

-This symlink points to:

-- `$XDG_STATE_HOME/profiles/channels` for regular users
-- `$NIX_STATE_DIR/profiles/per-user/root/channels` for `root`

-## Profiles
-
-A directory that contains links to profiles managed by [`nix-env`] and [`nix profile`]:
-
-- `$XDG_STATE_HOME/nix/profiles` for regular users
-- `$NIX_STATE_DIR/profiles/per-user/root` if the user is `root`
-
-A profile is a directory of symlinks to files in the Nix store.
-
-### Filesystem layout
-
-Profiles are versioned as follows. When using a profile named *path*, *path* is a symlink to *path*`-`*N*`-link`, where *N* is the version of the profile.
-In turn, *path*`-`*N*`-link` is a symlink to a path in the Nix store.
-For example:
-
-```console
-$ ls -l ~alice/.local/state/nix/profiles/profile*
-lrwxrwxrwx 1 alice users 14 Nov 25 14:35 /home/alice/.local/state/nix/profiles/profile -> profile-7-link

-# Name
-
-`nix-channel` - manage Nix channels
-
-# Synopsis
-
-`nix-channel` {`--add` url [*name*] | `--remove` *name* | `--list` | `--update` [*names…*] | `--list-generations` | `--rollback` [*generation*] }
-
-# Description
-
-Channels are a mechanism for referencing remote Nix expressions and conveniently retrieving their latest version.
-
-The moving parts of channels are:
-- The official channels listed at <https://nixos.org/channels>
-- The user-specific list of [subscribed channels](#subscribed-channels)
-- The [downloaded channel contents](#channels)
-- The [Nix expression search path](@docroot@/command-ref/conf-file.md#conf-nix-path), set with the [`-I` option](#opt-i) or the [`NIX_PATH` environment variable](#env-NIX_PATH)
-
-> **Note**
->
-> The state of a subscribed channel is external to the Nix expressions relying on it.
-> This may limit reproducibility.
->
-> Dependencies on other Nix expressions can be declared explicitly with:
-> - [`fetchurl`](@docroot@/language/builtins.md#builtins-fetchurl), [`fetchTarball`](@docroot@/language/builtins.md#builtins-fetchTarball), or [`fetchGit`](@docroot@/language/builtins.md#builtins-fetchGit) in Nix expressions
-> - the [`-I` option](@docroot@/command-ref/opt-common.md#opt-I) in command line invocations
-
-This command has the following operations:
-
-- `--add` *url* \[*name*\]
-
-  Add a channel *name* located at *url* to the list of subscribed channels.
-  If *name* is omitted, default to the last component of *url*, with the suffixes `-stable` or `-unstable` removed.
-
-  > **Note**
-  >
-  > `--add` does not automatically perform an update.
-  > Use `--update` explicitly.
-
-  A channel URL must point to a directory containing a file `nixexprs.tar.gz`.
-  At the top level, that tarball must contain a single directory with a `default.nix` file that serves as the channel’s entry point.
-
-- `--remove` *name*
-
-  Remove the channel *name* from the list of subscribed channels.
-
-- `--list`
-
-  Print the names and URLs of all subscribed channels on standard output.
-
-- `--update` \[*names*…\]
-
-  Download the Nix expressions of subscribed channels and create a new generation.
-  Update all channels if none is specified, and only those included in *names* otherwise.
-
-  > **Note**
-  >
-  > Downloaded channel contents are cached.
-  > Use `--tarball-ttl` or the [`tarball-ttl` configuration option](@docroot@/command-ref/conf-file.md#conf-tarball-ttl) to change the validity period of cached downloads.
-
-- `--list-generations`
-
-  Prints a list of all the current existing generations for the
-  channel profile.
-
-  Works the same way as
-  ```
-  nix-env --profile /nix/var/nix/profiles/per-user/$USER/channels --list-generations
-  ```
-
-- `--rollback` \[*generation*\]
-
-  Revert channels to the state before the last call to `nix-channel --update`.
-  Optionally, you can specify a specific channel *generation* number to restore.

-`nix-channel` operates on the following files.
-
-{{#include ./files/channels.md}}
-
-# Examples
-
-Subscribe to the Nixpkgs channel and run `hello` from the GNU Hello package:
-
-```console
-$ nix-channel --add https://nixos.org/channels/nixpkgs-unstable
-$ nix-channel --list
-nixpkgs https://nixos.org/channels/nixpkgs
-$ nix-channel --update
-$ nix-shell -p hello --run hello
-hello
-```
-
-Revert channel updates using `--rollback`:
-

-# Name
-
-`nix-collect-garbage` - delete unreachable [store objects]
-
-# Synopsis
-
-`nix-collect-garbage` [`--delete-old`] [`-d`] [`--delete-older-than` *period*] [`--max-freed` *bytes*] [`--dry-run`]
-
-# Description
-
-The command `nix-collect-garbage` is mostly an alias of [`nix-store --gc`](@docroot@/command-ref/nix-store/gc.md).
-That is, it deletes all unreachable [store objects] in the Nix store to clean up your system.
-
-However, it provides two additional options,
-[`--delete-old`](#opt-delete-old) and [`--delete-older-than`](#opt-delete-older-than),
-which also delete old [profiles], allowing potentially more [store objects] to be deleted because profiles are also garbage collection roots.
-These options are the equivalent of running
-[`nix-env --delete-generations`](@docroot@/command-ref/nix-env/delete-generations.md)
-with various augments on multiple profiles,
-prior to running `nix-collect-garbage` (or just `nix-store --gc`) without any flags.
-
-> **Note**
->
-> Deleting previous configurations makes rollbacks to them impossible.
-
-These flags should be used with care, because they potentially delete generations of profiles used by other users on the system.
-
-## Locations searched for profiles
-
-`nix-collect-garbage` cannot know about all profiles; that information doesn't exist.
-Instead, it looks in a few locations, and acts on all profiles it finds there:
-
-1. The default profile locations as specified in the [profiles] section of the manual.

-   `$NIX_STATE_DIR/profiles` and `$NIX_STATE_DIR/profiles/per-user`.
-
-   With the exception of `$NIX_STATE_DIR/profiles/per-user/root` and `$NIX_STATE_DIR/profiles/default`, these directories are no longer used by other commands.
-   `nix-collect-garbage` looks there anyways in order to clean up profiles from older versions of Nix.
-
-# Options
-
-These options are for deleting old [profiles] prior to deleting unreachable [store objects].
-
-- <span id="opt-delete-old">[`--delete-old`](#opt-delete-old)</span> / `-d`
-
-  Delete all old generations of profiles.
-
-  This is the equivalent of invoking [`nix-env --delete-generations old`](@docroot@/command-ref/nix-env/delete-generations.md#generations-old) on each found profile.
-
-- <span id="opt-delete-older-than">[`--delete-older-than`](#opt-delete-older-than)</span> *period*
-
-  Delete all generations of profiles older than the specified amount (except for the generations that were active at that point in time).
-  *period* is a value such as `30d`, which would mean 30 days.
-
-  This is the equivalent of invoking [`nix-env --delete-generations <period>`](@docroot@/command-ref/nix-env/delete-generations.md#generations-time) on each found profile.

-# Name
-
-`nix-copy-closure` - copy store objects to or from a remote machine via SSH
-
-# Synopsis

-  [`--gzip`]
-  [`--include-outputs`]
-  [`--use-substitutes` | `-s`]
-  [`-v`]
-  [_user_@]_machine_[:_port_] _paths_
-
-# Description
-
-Given _paths_ from one machine, `nix-copy-closure` computes the [closure](@docroot@/glossary.md#gloss-closure) of those paths (i.e. all their dependencies in the Nix store), and copies [store objects](@docroot@/glossary.md#gloss-store-object) in that closure to another machine via SSH.
-It doesn’t copy store objects that are already present on the other machine.
-
-> **Note**
->
-> While the Nix store to use on the local machine can be specified on the command line with the [`--store`](@docroot@/command-ref/conf-file.md#conf-store) option, the Nix store to be accessed on the remote machine can only be [configured statically](@docroot@/command-ref/conf-file.md#configuration-file) on that remote machine.
-
-Since `nix-copy-closure` calls `ssh`, you may need to authenticate with the remote machine.
-In fact, you may be asked for authentication _twice_ because `nix-copy-closure` currently connects twice to the remote machine: first to get the set of paths missing on the target machine, and second to send the dump of those paths.
-When using public key authentication, you can avoid typing the passphrase with `ssh-agent`.
-
-# Options
-
-- `--to`
-
-  Copy the closure of _paths_ from a Nix store accessible from the local machine to the Nix store on the remote _machine_.
-  This is the default behavior.
-
-- `--from`
-
-  Copy the closure of _paths_ from the Nix store on the remote _machine_ to the local machine's specified Nix store.
-
-- `--gzip`
-
-  Enable compression of the SSH connection.
-
-- `--include-outputs`
-
-  Also copy the outputs of [store derivation]s included in the closure.
-
-  [store derivation]: @docroot@/glossary.md#gloss-store-derivation
-
-- `--use-substitutes` / `-s`
-
-  Attempt to download missing store objects on the target from [substituters](@docroot@/command-ref/conf-file.md#conf-substituters).
-  Any store objects that cannot be substituted on the target are still copied normally from the source.
-  This is useful, for instance, if the connection between the source and target machine is slow, but the connection between the target machine and `cache.nixos.org` (the default binary cache server) is fast.

-# Name
-
-`nix-env` - manipulate or query Nix user environments
-
-# Synopsis
-
-`nix-env` *operation* [*options*] [*arguments…*]
-  [`--option` *name* *value*]
-  [`--arg` *name* *value*]
-  [`--argstr` *name* *value*]
-  [{`--file` | `-f`} *path*]
-  [{`--profile` | `-p`} *path*]
-  [`--system-filter` *system*]
-  [`--dry-run`]
-
-# Description
-
-The command `nix-env` is used to manipulate Nix user environments. User
-environments are sets of software packages available to a user at some
-point in time. In other words, they are a synthesised view of the
-programs available in the Nix store. There may be many user
-environments: different users can have different environments, and
-individual users can switch between different environments.
-
-`nix-env` takes exactly one *operation* flag which indicates the
-subcommand to be performed. The following operations are available:
-
-- [`--install`](./nix-env/install.md)
-- [`--upgrade`](./nix-env/upgrade.md)
-- [`--uninstall`](./nix-env/uninstall.md)
-- [`--set`](./nix-env/set.md)
-- [`--set-flag`](./nix-env/set-flag.md)
-- [`--query`](./nix-env/query.md)
-- [`--switch-profile`](./nix-env/switch-profile.md)
-- [`--list-generations`](./nix-env/list-generations.md)
-- [`--delete-generations`](./nix-env/delete-generations.md)
-- [`--switch-generation`](./nix-env/switch-generation.md)
-- [`--rollback`](./nix-env/rollback.md)
-
-These pages can be viewed offline:
-
-- `man nix-env-<operation>`.
-
-  Example: `man nix-env-install`
-
-- `nix-env --help --<operation>`
-
-  Example: `nix-env --help --install`
-
-# Package sources
-
-`nix-env` can obtain packages from multiple sources:
-
-- An attribute set of derivations from:
-  - The [default Nix expression](@docroot@/command-ref/files/default-nix-expression.md) (by default)
-  - A Nix file, specified via `--file`
-  - A [profile](@docroot@/command-ref/files/profiles.md), specified via `--from-profile`
-  - A Nix expression that is a function which takes default expression as argument, specified via `--from-expression`
-- A [store path](@docroot@/store/store-path.md)
-
-# Selectors
-
-Several operations, such as [`nix-env --query`](./nix-env/query.md) and [`nix-env --install`](./nix-env/install.md), take a list of *arguments* that specify the packages on which to operate.
-
-Packages are identified based on a `name` part and a `version` part of a [symbolic derivation name](@docroot@/language/derivations.md#attr-name):
-
-- `name`: Everything up to but not including the first dash (`-`) that is *not* followed by a letter.
-- `version`: The rest, excluding the separating dash.
-
-> **Example**
->
-> `nix-env` parses the symbolic derivation name `apache-httpd-2.0.48` as:
->
-> ```json
-> {
->   "name": "apache-httpd",
->   "version": "2.0.48"
-> }
-> ```
-
-> **Example**
->
-> `nix-env` parses the symbolic derivation name `firefox.*` as:
->
-> ```json
-> {
->   "name": "firefox.*",
->   "version": ""
-> }
-> ```
-
-The `name` parts of the *arguments* to `nix-env` are treated as extended regular expressions and matched against the `name` parts of derivation names in the package source.
-The match is case-sensitive.
-The regular expression can optionally be followed by a dash (`-`) and a version number; if omitted, any version of the package will match.
-For details on regular expressions, see [**regex**(7)](https://linux.die.net/man/7/regex).
-
-> **Example**
->
-> Common patterns for finding package names with `nix-env`:
->
-> - `firefox`
->
->   Matches the package name `firefox` and any version.
->
-> - `firefox-32.0`
->
->   Matches the package name `firefox` and version `32.0`.
->
-> - `gtk\\+`
->
->   Matches the package name `gtk+`.
->   The `+` character must be escaped using a backslash (`\`) to prevent it from being interpreted as a quantifier, and the backslash must be escaped in turn with another backslash to ensure that the shell passes it on.
->
-> - `.\*`
->
->   Matches any package name.
->   This is the default for most commands.
->
-> - `'.*zip.*'`
->
->   Matches any package name containing the string `zip`.
->   Note the dots: `'*zip*'` does not work, because in a regular expression, the character `*` is interpreted as a quantifier.
->
-> - `'.*(firefox|chromium).*'`
->
->   Matches any package name containing the strings `firefox` or `chromium`.

-  > One might expect this to just delete older generations than the current one, but that is only true if the current generation is also the latest.
-  > Because one can roll back to a previous generation, it is possible to have generations newer than the current one.
-  > They will also be deleted.
-
-- <span id="generations-time">[`<number>d`](#generations-time)</span>
-
-  The last *number* days
-
-  *Example*: `30d`
-
-  Delete all generations created more than *number* days ago, except the most recent one of them.
-  This allows rolling back to generations that were available within the specified period.

-
-  *Example*: `+5`
-
-  Keep the last *number* generations, along with any newer than current.
-
-Periodically deleting old generations is important to make garbage collection

-
-# Description
-
-The `--install` operation creates a new user environment.
-It is based on the current generation of the active [profile](@docroot@/command-ref/files/profiles.md), to which a set of [store paths] described by *args* is added.
-
-[store paths]: @docroot@/store/store-path.md
-
-The arguments *args* map to store paths in a number of possible ways:
-
-- By default, *args* is a set of names denoting derivations in the [default Nix expression].
-  These are [realised], and the resulting output paths are installed.
-  Currently installed derivations with a name equal to the name of a derivation being added are removed unless the option `--preserve-installed` is specified.
-
-  [derivation expression]: @docroot@/glossary.md#gloss-derivation-expression
-  [default Nix expression]: @docroot@/command-ref/files/default-nix-expression.md
-  [realised]: @docroot@/glossary.md#gloss-realise
-
-  If there are multiple derivations matching a name in *args* that
-  have the same name (e.g., `gcc-3.3.6` and `gcc-4.1.1`), then the
-  derivation with the highest *priority* is used. A derivation can
-  define a priority by declaring the `meta.priority` attribute. This
-  attribute should be a number, with a higher value denoting a lower
-  priority. The default priority is `5`.
-
-  If there are multiple matching derivations with the same priority,
-  then the derivation with the highest version will be installed.
-
-  You can force the installation of multiple derivations with the same
-  name by being specific about the versions. For instance, `nix-env --install
-  gcc-3.3.6 gcc-4.1.1` will install both version of GCC (and will
-  probably cause a user environment conflict\!).
-
-- If [`--attr`](#opt-attr) / `-A` is specified, the arguments are *attribute paths* that select attributes from the [default Nix expression].
-  This is faster than using derivation names and unambiguous.
-  Show the attribute paths of available packages with [`nix-env --query`](./query.md):
-
-  ```console
-  nix-env --query --available --attr-path
-  ```
-
-- If `--from-profile` *path* is given, *args* is a set of names
-  denoting installed [store paths] in the profile *path*. This is an
-  easy way to copy user environment elements from one profile to
-  another.
-
-- If `--from-expression` is given, *args* are [Nix language functions](@docroot@/language/syntax.md#functions) that are called with the [default Nix expression] as their single argument.
-  The derivations returned by those function calls are installed.
-  This allows derivations to be specified in an unambiguous way, which is necessary if there are multiple derivations with the same name.
-
-- If `--priority` *priority* is given, the priority of the derivations being installed is set to *priority*.
-  This can be used to override the priority of the derivations being installed.
-  This is useful if *args* are [store paths], which don't have any priority information.
-
-- If *args* are [store paths] that point to [store derivations][store derivation], then those store derivations are [realised], and the resulting output paths are installed.
-
-- If *args* are [store paths] that do not point to store derivations, then these are [realised] and installed.
-
-- By default all [outputs](@docroot@/language/derivations.md#attr-outputs) are installed for each [store derivation].
-  This can be overridden by adding a `meta.outputsToInstall` attribute on the derivation listing a subset of the output names.
-
-  Example:
-
-  The file `example.nix` defines a derivation with two outputs `foo` and `bar`, each containing a file.
-
-  ```nix
-  # example.nix
-  let
-    pkgs = import <nixpkgs> {};
-    command = ''
-      ${pkgs.coreutils}/bin/mkdir -p $foo $bar
-      echo foo > $foo/foo-file
-      echo bar > $bar/bar-file
-    '';
-  in
-  derivation {
-    name = "example";
-    builder = "${pkgs.bash}/bin/bash";
-    args = [ "-c" command ];
-    outputs = [ "foo" "bar" ];
-    system = builtins.currentSystem;
-  }
-  ```
-
-  Installing from this Nix expression will make files from both outputs appear in the current profile.
-
-  ```console
-  $ nix-env --install --file example.nix
-  installing 'example'
-  $ ls ~/.nix-profile
-  foo-file
-  bar-file
-  manifest.nix
-  ```
-
-  Adding `meta.outputsToInstall` to that derivation will make `nix-env` only install files from the specified outputs.
-
-  ```nix
-  # example-outputs.nix
-  import ./example.nix // { meta.outputsToInstall = [ "bar" ]; }
-  ```
-
-  ```console
-  $ nix-env --install --file example-outputs.nix
-  installing 'example'
-  $ ls ~/.nix-profile
-  bar-file
-  manifest.nix
-  ```
-
-[store derivation]: @docroot@/glossary.md#gloss-store-derivation
-
-# Options
-
-- `--prebuilt-only` / `-b`
-
-  Use only derivations for which a substitute is registered, i.e.,
-  there is a pre-built binary available that can be downloaded in lieu
-  of building the derivation. Thus, no packages will be built from
-  source.
-
-- `--preserve-installed` / `-P`
-
-  Do not remove derivations with a name matching one of the
-  derivations being installed. Usually, trying to have two versions of
-  the same package installed in the same generation of a profile will
-  lead to an error in building the generation, due to file name
-  clashes between the two versions. However, this is not the case for
-  all packages.
-
-- `--remove-all` / `-r`
-
-  Remove all previously installed packages first. This is equivalent
-  to running `nix-env --uninstall '.*'` first, except that everything happens
-  in a single transaction.

-# Examples
-
-To install a package using a specific attribute path from the active Nix expression:

-$ nix-env --install --attr gcc40mips
-installing `gcc-4.0.2'
-$ nix-env --install --attr xorg.xorgserver
-installing `xorg-server-1.2.0'
-```
-
-To install a specific version of `gcc` using the derivation name:
-
-```console
-$ nix-env --install gcc-3.3.2
-installing `gcc-3.3.2'
-uninstalling `gcc-3.1'
-```
-
-Using attribute path for selecting a package is preferred,
-as it is much faster and there will not be multiple matches.
-
-Note the previously installed version is removed, since
-`--preserve-installed` was not specified.
-
-To install an arbitrary version:
-
-```console
-$ nix-env --install gcc
-installing `gcc-3.3.2'
-```
-
-To install all derivations in the Nix expression `foo.nix`:
-
-```console
-$ nix-env --file ~/foo.nix --install '.*'
-```
-
-To copy the store path with symbolic name `gcc` from another profile:
-
-```console
-$ nix-env --install --from-profile /nix/var/nix/profiles/foo gcc
-```
-
-To install a specific [store derivation] (typically created by
-`nix-instantiate`):

-# Options
-
-The following options are allowed for all `nix-env` operations, but may not always have an effect.
-
-- `--file` / `-f` *path*
-
-  Specifies the Nix expression (designated below as the *active Nix
-  expression*) used by the `--install`, `--upgrade`, and `--query
-  --available` operations to obtain derivations. The default is
-  `~/.nix-defexpr`.
-
-  If the argument starts with `http://` or `https://`, it is
-  interpreted as the URL of a tarball that will be downloaded and
-  unpacked to a temporary location. The tarball must include a single
-  top-level directory containing at least a file named `default.nix`.
-
-- `--profile` / `-p` *path*
-
-  Specifies the profile to be used by those operations that operate on
-  a profile (designated below as the *active profile*). A profile is a
-  sequence of user environments called *generations*, one of which is
-  the *current generation*.
-
-- `--dry-run`
-
-  For the `--install`, `--upgrade`, `--uninstall`,
-  `--switch-generation`, `--delete-generations` and `--rollback`
-  operations, this flag will cause `nix-env` to print what *would* be
-  done if this flag had not been specified, without actually doing it.
-
-  `--dry-run` also prints out which paths will be
-  [substituted](@docroot@/glossary.md) (i.e., downloaded) and which paths
-  will be built from source (because no substitute is available).
-
-- `--system-filter` *system*
-
-  By default, operations such as `--query --available` show derivations matching any platform. This option
-  allows you to use derivations for the specified platform *system*.

-
-# Description
-
-The query operation displays information about either the store paths
-that are installed in the current generation of the active profile
-(`--installed`), or the derivations that are available for installation
-in the active Nix expression (`--available`). It only prints information
-about derivations whose symbolic name matches one of *names*.
-
-The derivations are sorted by their `name` attributes.
-
-# Source selection
-
-The following flags specify the set of things on which the query
-operates.
-
-  - `--installed`
-
-    The query operates on the store paths that are installed in the
-    current generation of the active profile. This is the default.
-
-  - `--available` / `-a`
-
-    The query operates on the derivations that are available in the
-    active Nix expression.
-
-# Queries
-
-The following flags specify what information to display about the
-selected derivations. Multiple flags may be specified, in which case the
-information is shown in the order given here. Note that the name of the
-derivation is shown unless `--no-name` is specified.
-
-  - `--xml`
-
-    Print the result in an XML representation suitable for automatic
-    processing by other tools. The root element is called `items`, which
-    contains a `item` element for each available or installed
-    derivation. The fields discussed below are all stored in attributes
-    of the `item` elements.
-
-  - `--json`
-
-    Print the result in a JSON representation suitable for automatic
-    processing by other tools.
-
-  - `--prebuilt-only` / `-b`
-
-    Show only derivations for which a substitute is registered, i.e.,
-    there is a pre-built binary available that can be downloaded in lieu
-    of building the derivation. Thus, this shows all packages that
-    probably can be installed quickly.
-
-  - `--status` / `-s`
-
-    Print the *status* of the derivation. The status consists of three
-    characters. The first is `I` or `-`, indicating whether the
-    derivation is currently installed in the current generation of the
-    active profile. This is by definition the case for `--installed`,
-    but not for `--available`. The second is `P` or `-`, indicating
-    whether the derivation is present on the system. This indicates
-    whether installation of an available derivation will require the
-    derivation to be built. The third is `S` or `-`, indicating whether
-    a substitute is available for the derivation.
-
-  - `--attr-path` / `-P`
-
-    Print the *attribute path* of the derivation, which can be used to
-    unambiguously select it using the `--attr` option available in
-    commands that install derivations like `nix-env --install`. This
-    option only works together with `--available`
-
-  - `--no-name`
-
-    Suppress printing of the `name` attribute of each derivation.
-
-  - `--compare-versions` / `-c`
-
-    Compare installed versions to available versions, or vice versa (if
-    `--available` is given). This is useful for quickly seeing whether
-    upgrades for installed packages are available in a Nix expression. A
-    column is added with the following meaning:
-
-      - `<` *version*
-
-        A newer version of the package is available or installed.
-
-      - `=` *version*
-
-        At most the same version of the package is available or
-        installed.
-
-      - `>` *version*
-
-        Only older versions of the package are available or installed.
-
-      - `- ?`
-
-        No version of the package is available or installed.
-
-  - `--system`
-
-    Print the `system` attribute of the derivation.
-
-  - `--drv-path`
-
-    Print the [store path] to the [store derivation].
-
-    [store path]: @docroot@/glossary.md#gloss-store-path
-    [store derivation]: @docroot@/glossary.md#gloss-derivation
-
-  - `--out-path`
-
-    Print the output path of the derivation.
-
-  - `--description`
-
-    Print a short (one-line) description of the derivation, if
-    available. The description is taken from the `meta.description`
-    attribute of the derivation.
-
-  - `--meta`
-
-    Print all of the meta-attributes of the derivation. This option is
-    only available with `--xml` or `--json`.

-
-# Description
-
-The `--set-flag` operation allows meta attributes of installed packages
-to be modified. There are several attributes that can be usefully
-modified, because they affect the behaviour of `nix-env` or the user
-environment build script:
-
-- `priority` can be changed to resolve filename clashes. The user
-  environment build script uses the `meta.priority` attribute of
-  derivations to resolve filename collisions between packages. Lower
-  priority values denote a higher priority. For instance, the GCC
-  wrapper package and the Binutils package in Nixpkgs both have a file
-  `bin/ld`, so previously if you tried to install both you would get a
-  collision. Now, on the other hand, the GCC wrapper declares a higher
-  priority than Binutils, so the former’s `bin/ld` is symlinked in the
-  user environment.
-
-- `keep` can be set to `true` to prevent the package from being
-  upgraded or replaced. This is useful if you want to hang on to an
-  older version of a package.
-
-- `active` can be set to `false` to “disable” the package. That is, no
-  symlinks will be generated to the files of the package, but it
-  remains part of the profile (so it won’t be garbage-collected). It
-  can be set back to `true` to re-enable the package.

-For a description of how *args* is mapped to a set of store paths, see

-
-# Flags
-
-- `--lt`
-
-  Only upgrade a derivation to newer versions. This is the default.
-
-- `--leq`
-
-  In addition to upgrading to newer versions, also “upgrade” to
-  derivations that have the same version. Version are not a unique
-  identification of a derivation, so there may be many derivations
-  that have the same version. This flag may be useful to force
-  “synchronisation” between the installed and available derivations.
-
-- `--eq`
-
-  *Only* “upgrade” to derivations that have the same version. This may
-  not seem very useful, but it actually is, e.g., when there is a new
-  release of Nixpkgs and you want to replace installed applications
-  with the same versions built against newer dependencies (to reduce
-  the number of dependencies floating around on your system).
-
-- `--always`
-
-  In addition to upgrading to newer versions, also “upgrade” to
-  derivations that have the same or a lower version. I.e., derivations
-  may actually be downgraded depending on what is available in the
-  active Nix expression.
-
-- `--prebuilt-only` / `-b`
-
-  Use only derivations for which a substitute is registered, i.e.,
-  there is a pre-built binary available that can be downloaded in lieu
-  of building the derivation. Thus, no packages will be built from
-  source.
-
-- `--preserve-installed` / `-P`
-
-  Do not remove derivations with a name matching one of the
-  derivations being installed. Usually, trying to have two versions of
-  the same package installed in the same generation of a profile will
-  lead to an error in building the generation, due to file name
-  clashes between the two versions. However, this is not the case for
-  all packages.

-```
-
-When there are no updates available, nothing will happen:
-
-```console
-$ nix-env --upgrade --attr nixpkgs.pan
-```
-
-Using `-A` is preferred when possible, as it is faster and unambiguous but
-it is also possible to upgrade to a specific version by matching the derivation name:
-
-```console
-$ nix-env --upgrade gcc-3.3.2 --always
-upgrading `gcc-3.4' to `gcc-3.3.2'

-upgrading `hello-2.1.2' to `hello-2.1.3'
-upgrading `mozilla-1.2' to `mozilla-1.4'
-```
-
-# Versions
-
-The upgrade operation determines whether a derivation `y` is an upgrade
-of a derivation `x` by looking at their respective `name` attributes.
-The names (e.g., `gcc-3.3.1` are split into two parts: the package name
-(`gcc`), and the version (`3.3.1`). The version part starts after the
-first dash not followed by a letter. `y` is considered an upgrade of `x`
-if their package names match, and the version of `y` is higher than that
-of `x`.
-
-The versions are compared by splitting them into contiguous components
-of numbers and letters. E.g., `3.3.1pre5` is split into `[3, 3, 1,
-"pre", 5]`. These lists are then compared lexicographically (from left
-to right). Corresponding components `a` and `b` are compared as follows.
-If they are both numbers, integer comparison is used. If `a` is an empty
-string and `b` is a number, `a` is considered less than `b`. The special
-string component `pre` (for *pre-release*) is considered to be less than
-other components. String components are considered less than number
-components. Otherwise, they are compared lexicographically (i.e., using
-case-sensitive string comparison).
-
-This is illustrated by the following examples:
-
-    1.0 < 2.3
-    2.1 < 2.3
-    2.3 = 2.3
-    2.5 > 2.3
-    3.1 > 2.3

-    2.3.1 > 2.3a

-`nix-prefetch-url` you have to specify multiple arguments, see below for
-an example.
-
-The hash is computed over a *serialisation* of each path: a dump of
-the file system tree rooted at the path. This allows directories and
-symlinks to be hashed as well as regular files. The dump is in the
-*[Nix Archive (NAR)][Nix Archive] format* produced by [`nix-store
---dump`](@docroot@/command-ref/nix-store/dump.md).  Thus, `nix-hash path`
-yields the same cryptographic hash as `nix-store --dump path |
-md5sum`.
-
-[Nix Archive]: @docroot@/store/file-system-object/content-address.md#serial-nix-archive
-
-# Options
-
-- `--flat`
-
-  Print the cryptographic hash of the contents of each regular file *path*.
-  That is, instead of computing
-  the hash of the [Nix Archive (NAR)](@docroot@/store/file-system-object/content-address.md#serial-nix-archive) of *path*,
-  just [directly hash]((@docroot@/store/file-system-object/content-address.md#serial-flat) *path* as is.
-  This requires *path* to resolve to a regular file rather than directory.
-  The result is identical to that produced by the GNU commands
-  `md5sum` and `sha1sum`.
-
-- `--base16`
-
-  Print the hash in a hexadecimal representation (default).
-
-- `--base32`
-
-  Print the hash in a base-32 representation rather than hexadecimal.
-  This base-32 representation is more compact and can be used in Nix
-  expressions (such as in calls to `fetchurl`).
-
-- `--base64`
-
-  Similar to --base32, but print the hash in a base-64 representation,
-  which is more compact than the base-32 one.
-
-- `--sri`
-
-  Print the hash in SRI format with base-64 encoding.
-  The type of hash algorithm will be prepended to the hash string,
-  followed by a hyphen (-) and the base-64 hash body.
-
-- `--truncate`
-
-  Truncate hashes longer than 160 bits (such as SHA-256) to 160 bits.
-
-- `--type` *hashAlgo*
-
-  Use the specified cryptographic hash algorithm, which can be one of
-  `blake3`, `md5`, `sha1`, `sha256`, and `sha512`.
-
-- `--to-base16`
-
-  Don’t hash anything, but convert the base-32 hash representation
-  *hash* to hexadecimal.
-
-- `--to-base32`
-
-  Don’t hash anything, but convert the hexadecimal hash representation
-  *hash* to base-32.
-
-- `--to-base64`
-
-  Don’t hash anything, but convert the hexadecimal hash representation
-  *hash* to base-64.
-
-- `--to-sri`
-
-  Don’t hash anything, but convert the hexadecimal hash representation
-  *hash* to SRI.

-# Name
-
-`nix-instantiate` - instantiate store derivations from Nix expressions
-
-# Synopsis
-
-`nix-instantiate`
-  [`--parse` | `--eval` [`--strict`] [`--raw` | `--json` | `--xml`] ]
-  [`--read-write-mode`]
-  [`--arg` *name* *value*]
-  [{`--attr`| `-A`} *attrPath*]

-  [`--expr` | `-E`]
-  *files…*
-
-`nix-instantiate` `--find-file` *files…*
-
-# Description
-
-The command `nix-instantiate` produces [store derivation]s from (high-level) Nix expressions.
-It evaluates the Nix expressions in each of *files* (which defaults to
-*./default.nix*). Each top-level expression should evaluate to a
-derivation, a list of derivations, or a set of derivations. The paths
-of the resulting store derivations are printed on standard output.
-
-[store derivation]: @docroot@/glossary.md#gloss-store-derivation
-
-If *files* is the character `-`, then a Nix expression will be read from
-standard input.
-
-# Options
-
-- `--add-root` *path*
-
-  See the [corresponding option](nix-store.md) in `nix-store`.
-
-- `--parse`
-
-  Just parse the input files, and print their abstract syntax trees on
-  standard output as a Nix expression.
-
-- `--eval`
-
-  Just parse and evaluate the input files, and print the resulting
-  values on standard output.
-  Store derivations are not serialized and written to the store, but instead just hashed and discarded.
-
-  > **Warning**
-  >
-  > This option produces output which can be parsed as a Nix expression which
-  > will produce a different result than the input expression when evaluated.
-  > For example, these two Nix expressions print the same result despite
-  > having different meaning:
-  >
-  > ```console
-  > $ nix-instantiate --eval --expr '{ a = {}; }'
-  > { a = <CODE>; }
-  > $ nix-instantiate --eval --expr '{ a = <CODE>; }'
-  > { a = <CODE>; }
-  > ```
-  >
-  > For human-readable output, `nix eval` (experimental) is more informative:
-  >
-  > ```console
-  > $ nix-instantiate --eval --expr 'a: a'
-  > <LAMBDA>
-  > $ nix eval --expr 'a: a'
-  > «lambda @ «string»:1:1»
-  > ```
-  >
-  > For machine-readable output, the `--xml` option produces unambiguous
-  > output:
-  >
-  > ```console
-  > $ nix-instantiate --eval --xml --expr '{ foo = <CODE>; }'
-  > <?xml version='1.0' encoding='utf-8'?>
-  > <expr>
-  >   <attrs>
-  >     <attr column="3" line="1" name="foo">
-  >       <unevaluated />
-  >     </attr>
-  >   </attrs>
-  > </expr>
-  > ```
-
-- `--find-file`
-
-  Look up the given files in Nix’s search path (as specified by the
-  `NIX_PATH` environment variable). If found, print the corresponding
-  absolute paths on standard output. For instance, if `NIX_PATH` is
-  `nixpkgs=/home/alice/nixpkgs`, then `nix-instantiate --find-file
-  nixpkgs/default.nix` will print `/home/alice/nixpkgs/default.nix`.
-
-- `--strict`
-
-  When used with `--eval`, recursively evaluate list elements and
-  attributes. Normally, such sub-expressions are left unevaluated
-  (since the Nix language is lazy).
-
-  > **Warning**
-  >
-  > This option can cause non-termination, because lazy data
-  > structures can be infinitely large.
-
-- `--raw`
-
-  When used with `--eval`, the evaluation result must be a string,
-  which is printed verbatim, without quoting, escaping or trailing newline.
-
-- `--json`
-
-  When used with `--eval`, print the resulting value as an JSON
-  representation of the abstract syntax tree rather than as a Nix expression.
-
-- `--xml`
-
-  When used with `--eval`, print the resulting value as an XML
-  representation of the abstract syntax tree rather than as a Nix expression.
-  The schema is the same as that used by the [`toXML`
-  built-in](../language/builtins.md).
-
-- `--read-write-mode`
-
-  When used with `--eval`, perform evaluation in read/write mode so
-  nix language features that require it will still work (at the cost
-  of needing to do instantiation of every evaluated derivation). If
-  this option is not enabled, there may be uninstantiated store paths
-  in the final output.
-
-{{#include ./opt-common.md}}
-
-{{#include ./env-common.md}}
-
-# Examples
-
-Instantiate [store derivation]s from a Nix expression, and build them using `nix-store`:
-
-```console
-$ nix-instantiate test.nix (instantiate)
-/nix/store/cigxbmvy6dzix98dxxh9b6shg7ar5bvs-perl-BerkeleyDB-0.26.drv
-
-$ nix-store --realise $(nix-instantiate test.nix) (build)

-dr-xr-xr-x    2 eelco    users        4096 1970-01-01 01:00 lib
-...
-```
-
-You can also give a Nix expression on the command line:
-
-```console
-$ nix-instantiate --expr 'with import <nixpkgs> { }; hello'
-/nix/store/j8s4zyv75a724q38cb0r87rlczaiag4y-hello-2.8.drv
-```
-
-This is equivalent to:
-
-```console
-$ nix-instantiate '<nixpkgs>' --attr hello
-```
-
-Parsing and evaluating Nix expressions:
-
-```console
-$ nix-instantiate --parse --expr '1 + 2'
-1 + 2
-```
-
-```console
-$ nix-instantiate --eval --expr '1 + 2'
-3
-```
-

-$ nix-instantiate --eval --xml --expr '1 + 2'
-<?xml version='1.0' encoding='utf-8'?>
-<expr>
-  <int value="3" />
-</expr>
-```
-
-The difference between non-strict and strict evaluation:

-```console
-$ nix-instantiate --eval --xml --expr '{ x = {}; }'
-<?xml version='1.0' encoding='utf-8'?>
-<expr>
-  <attrs>
-    <attr column="3" line="1" name="x">

-`nix-store --dump` - write a single path to a [Nix Archive]
-
-## Synopsis
-
-`nix-store` `--dump` *path*
-
-## Description
-
-The operation `--dump` produces a [Nix archive](@docroot@/glossary.md#gloss-nar) (NAR) file containing the
-contents of the file system tree rooted at *path*. The archive is
-written to standard output.
-
-A NAR archive is like a TAR or Zip archive, but it contains only the
-information that Nix considers important. For instance, timestamps are
-elided because all files in the Nix store have their timestamp set to 0
-anyway. Likewise, all permissions are left out except for the execute
-bit, because all files in the Nix store have 444 or 555 permission.
-
-Also, a NAR archive is *canonical*, meaning that “equal” paths always
-produce the same NAR archive. For instance, directory entries are
-always sorted so that the actual on-disk order doesn’t influence the
-result.  This means that the cryptographic hash of a NAR dump of a
-path is usable as a fingerprint of the contents of the path. Indeed,
-the hashes of store paths stored in Nix’s database (see `nix-store --query
---hash`) are SHA-256 hashes of the NAR dump of each store path.
-
-NAR archives support filenames of unlimited length and 64-bit file
-sizes. They can contain regular files, directories, and symbolic links,
-but not other types of files (such as device nodes).
-
-A Nix archive can be unpacked using [`nix-store --restore`](@docroot@/command-ref/nix-store/restore.md).

-`nix-store` `--gc` [`--print-roots` | `--print-live` | `--print-dead`] [`--max-freed` *bytes*]
-
-# Description
-
-Without additional flags, the operation `--gc` performs a garbage
-collection on the Nix store. That is, all paths in the Nix store not
-reachable via file system references from a set of “roots”, are deleted.
-
-The following suboperations may be specified:
-
-- `--print-roots`
-
-  This operation prints on standard output the set of roots used by
-  the garbage collector.
-
-- `--print-live`
-
-  This operation prints on standard output the set of “live” store
-  paths, which are all the store paths reachable from the roots. Live
-  paths should never be deleted, since that would break consistency —
-  it would become possible that applications are installed that
-  reference things that are no longer present in the store.
-
-- `--print-dead`
-
-  This operation prints out on standard output the set of “dead” store
-  paths, which is just the opposite of the set of live paths: any path
-  in the store that is not live (with respect to the roots) is dead.
-
-By default, all unreachable paths are deleted. The following options
-control what gets deleted and in what order:
-
-- `--max-freed` *bytes*
-
-  Keep deleting paths until at least *bytes* bytes have been deleted,
-  then stop. The argument *bytes* can be followed by the
-  multiplicative suffix `K`, `M`, `G` or `T`, denoting KiB, MiB, GiB
-  or TiB units.
-
-The behaviour of the collector is also influenced by the
-`keep-outputs` and `keep-derivations` settings in the Nix
-configuration file.
-
-By default, the collector prints the total number of freed bytes when it
-finishes (or when it is interrupted). With `--print-dead`, it prints the

-`nix-store --generate-binary-cache-key` - generate key pair to use for a binary cache
-
-## Synopsis
-
-`nix-store` `--generate-binary-cache-key` *key-name* *secret-key-file* *public-key-file*
-
-## Description
-
-This command generates an [Ed25519 key pair](http://ed25519.cr.yp.to/)
-that can be used to create a signed binary cache. It takes three
-mandatory parameters:
-
-1.  A key name, such as `cache.example.org-1`, that is used to look up
-    keys on the client when it verifies signatures. It can be anything,
-    but it’s suggested to use the host name of your cache (e.g.
-    `cache.example.org`) with a suffix denoting the number of the key
-    (to be incremented every time you need to revoke a key).
-
-2.  The file name where the secret key is to be stored.
-
-3.  The file name where the public key is to be stored.

-# Name
-
-`nix-store --import` - import [Nix Archive] into the store
-
-[Nix Archive]: @docroot@/store/file-system-object/content-address.md#serial-nix-archive
-
-# Synopsis
-
-`nix-store` `--import`
-
-# Description
-
-The operation `--import` reads a serialisation of a set of [store objects](@docroot@/glossary.md#gloss-store-object) produced by [`nix-store --export`](./export.md) from standard input, and adds those store objects to the specified [Nix store](@docroot@/store/index.md).
-Paths that already exist in the target Nix store are ignored.
-If a path [refers](@docroot@/glossary.md#gloss-reference) to another path that doesn’t exist in the target Nix store, the import fails.

-The following options are allowed for all `nix-store` operations, but may not always have an effect.

-- <span id="opt-add-root">[`--add-root`](#opt-add-root)</span> *path*
-
-  Causes the result of a realisation (`--realise` and
-  `--force-realise`) to be registered as a root of the garbage
-  collector. *path* will be created as a symlink to the resulting
-  store path. In addition, a uniquely named symlink to *path* will
-  be created in `/nix/var/nix/gcroots/auto/`. For instance,
-
-  ```console
-  $ nix-store --add-root /home/eelco/bla/result --realise ...
-
-  $ ls -l /nix/var/nix/gcroots/auto
-  lrwxrwxrwx    1 ... 2005-03-13 21:10 dn54lcypm8f8... -> /home/eelco/bla/result
-
-  $ ls -l /home/eelco/bla/result
-  lrwxrwxrwx    1 ... 2005-03-13 21:10 /home/eelco/bla/result -> /nix/store/1r11343n6qd4...-f-spot-0.0.10
-  ```
-
-  Thus, when `/home/eelco/bla/result` is removed, the GC root in the
-  `auto` directory becomes a dangling symlink and will be ignored by
-  the collector.
-
-  > **Warning**
-  >
-  > Note that it is not possible to move or rename GC roots, since
-  > the symlink in the `auto` directory will still point to the old
-  > location.
-
-  If there are multiple results, then multiple symlinks will be
-  created by sequentially numbering symlinks beyond the first one
-  (e.g., `foo`, `foo-2`, `foo-3`, and so on).
