 ## Why
-You might already be happy with your choice of an OC emulator; after all, there
-is already a plenty of them.
-So why would you want to reconsider your life choices now all of a sudden?
+You might already be happy with your choice of an OC emulator;
+there is a plenty of them, after all.
+Why would you want to reconsider your life choices now all of a sudden?
 A fine question, indeed; perhaps, a list of features will persuade you.
 
 ### Powered by ocelot-brain
 At the heart of this emulator is [ocelot-brain][ocelot-brain] (uh, don't ask me),
-which is essentially the source code of OpenComputers stripped of everything
-Minecraft-specific and packaged as a Scala library.
+which is essentially the source code of OpenComputers decoupled of everything
+Minecraft-specific and repurposed as a Scala library.
 This makes Ocelot Desktop **the most accurate emulator** ever made.
-Your programs will run on the same version of Lua as used by the mod and have
+Your programs will run on the Lua implementation used by the mod and exhibit
 similar timings.
 The performance and memory constraints present in OC are also emulated.
 
 ### Customizable setups
-Computers can have the following components:
+Taylor your computer build to your needs!
+We provide a variety of components to choose from:
 
-- the 3 tiers of graphics cards
-- all kinds of network cards (wired, wireless)
-- a linked card
-- an internet card
-- a sound card (Computronics)
-- a redstone card in the both tiers
-- a data card (again, you can pick any of the three tiers)
+- graphics cards
+- network cards (wired, wireless)
+- linked cards
+- internet cards
+- redstone cards (including the second tier!)
+- data cards
 - hard disks
-- a floppy disk (in T3+ computer cases only)
+- floppy disks (in T3+ computer cases only, just like in OpenComputers)
 
-The choice is restricted by the tier of a computer case, just like in
-OpenComputers, to avoid building impossible configurations.
-Oh, did I forget to mention that Ocelot Desktop has both the CPUs and the APUs?
-Memory can likewise be installed according to your needs.
+Feel limited by the vanilla cards?
+No problem — we've even integrated some components from popular addons!
 
-If one computer is not enough, you can add another one.
-Or two, or a thousand, as long as your host doesn't collapse under the load,
-of course.
-The network cards are there for a reason — these newly spawned machines can
-communicate with each other.
-And relays may help you manage the wired networks.
+![Addon showcase][addon-showcase]
 
-Or, instead of employing an army of computers, you might want to connect a dozen
-of screens to a single machine, like in the movies.
-No problem — we've got that covered, too.
+- **Computronics:**
+  - `computer.beep()` does not excite your music sense enough?
+    Check out the **sound card**'s synthesis engine,
+    or string notes together on a bunch of **note blocks**!
 
-### Pretty graphical interface
+  - You have privacy concerns?
+    An ultra-precision blast of the **self-destructing card** might save your day!
+
+  - If, on the contrary, you're the kind to violate the privacy of others,
+    we've got a **camera** that reads video data from a real webcam.
+
+  - Those who seem to find no color in their life may appreciate the
+    **colorful lamps**.
+    Their iridescent glow will provide comfort in the darkest hour.
+    And they won't desert you.
+
+- **OpenFM:** for those lo-fi beats to chill and relax to while writing code.
+
+We'll make sure your setups are grounded in reality
+by having the maximum card tier in a slot depend on your computer case.
+Oh, did I forget to mention Ocelot Desktop has APUs as well?
+
+Explore the wonders of distributed computing by adding a couple of other
+computers to your workspace.
+(Or a thousand — if you think your host can handle this.)
+Network cards allow these newly spawned machines to talk to each other.
+And relays may prove useful to manage the wired networks.
+
+Perhaps, instead of enlisting a computer army,
+you want to attach a dozen of screens to a single machine
+(as they do in the movies).
+Well, no problem — we've got that covered, too.
+
+### Gorgeous graphical interface
 ![GUI][gui]
 
-A slick interface allows you to customize the setup to your liking.
-Add more computers, organize the connections between components, build complex
-setups, and manage your screen real estate to avoid distractions.
+Manage your screen real estate to avoid distractions.
+All nodes are draggable, as are windows.
+And screen windows in particular are also resizeable —
+click and drag the bottom-right corner if they take up too much space.
+Or hold <kbd>Shift</kbd> and let the window consume it all.
 
-Many additional options are hidden in the context menu — try hitting the
-right mouse button on the various things.
-For example, components will let you copy their address to the clipboard, and
-right-clicking on the TPS counter on the bottom allows you to change the
-simulation speed.
+![Window scaling][window-scaling]
 
-The emulator uses hardware acceleration to offload the daunting task of
-rendering its interface to a specialized device, so make sure you have a OpenGL
-2.1-capable graphics card.

+![TPS rate menu][tps-menu]
+
+Ocelot Desktop uses hardware acceleration to offload the daunting task of
+rendering its interface to a special-purposed device (your GPU),
+so make sure you have an **OpenGL 2.1-capable** graphics card.
+(Though, honestly, it's harder to find one that isn't, really.)
 
 ### Persistable workspaces
-It would be sad if, after all the hard work you put into adjusting the
-workspace, you have to do that again.
+Imagine putting many hours into wiring things up only to have to do it all from
+scratch the next time you open the emulator.
+That... would be sad and disappointing.
 I mean, OpenComputers can persist its machines just fine, right?
-By basing the emulator on its code, we've essentially inherited the ability
-to save workspaces on the disk and load them afterwards.
+Good news: by reusing its code, we've essentially inherited the ability
+to save workspaces on the disk and load them afterwards!
 
 Just in case, Ocelot Desktop will warn you if you smash the quit button without
 saving.
+We'd rather you didn't feel sad and disappointed.
 
 ### Cool features
-![Performance graphs][graphs]
+![Performance graphs][perf-graphs]
 ![Sound card GUI][sound-card]
 
 A few smaller features are worth mentioning, too:
 
-- Screens are resizeable — drag the bottom-right corner.
-- Windows are labeled with the corresponding block's address; however, you can
-  set a custom label — look for an option in the context menu.
-- The button in a computer case window shows the performance graphs:
-  the used memory, processor time and call budget.
-- Hold the Ctrl key while dragging blocks to have them snap to the grid.
+- Windows show the corresponding block's address by default.
+  However, you can relabel them: look for the option in the context menu.
+- The button ![][drawer-button] at the bottom of a computer case window
+  shows performance graphs: the memory, processor time, and call budget.
+- Hold the <kbd>Ctrl</kbd> key while dragging blocks to snap them to the grid.

+Decided to give Ocelot Desktop a shot?
 
-## How to build it?
-Just import the project in your favorite IDE.  
-Make sure to have Scala and SBT installed (manually or through IDE).
+[**Download** the latest build][download] / [mirror][download-mirror]
 
-Ocelot Brain library is added as a Git submodule, so do not forget to fetch it too.  
-Something like `git submodule update --init --recursive` should do the trick.
+## Hacking
+Just import the project in your favorite IDE.
+Make sure to have Scala and SBT installed (your IDE may assist you with that).
 
-Use `sbt run` to start Ocelot Desktop. Use `sbt assembly` to generate JAR file.  
-(It will appear at `target/scala-2.13/ocelot-desktop.jar` location.)
+We include [ocelot-brain][] as a Git submodule: don't forget to fetch it!
 
-If the compiler is complaining about missing BuildInfo class, or the version in
-the window title / logs looks outdated, use `sbt buildInfo` to generate fresh class.
+```sh
+$ git submodule update --init --recursive
+```
+
+To build from source and start Ocelot Desktop, type:
+
+```sh
+$ sbt run
+```
+
+If you want to get a JAR, use this:
+
+```sh
+$ sbt assembly
+```
+
+(You'll find it at `target/scala-2.13/ocelot-desktop.jar`.)
+
+In case you see the compiler complain about `BuildInfo` or just want to refresh
+the version displayed in the window title and the logs, run:
+
+```sh
+$ sbt buildInfo
+```
