+      <p>
+        You can of course provide your own versions of the <code>project.jelly</code>
+        and <code>setup.jelly</code> templates. This requires you to understand NSIS
+        and a little bit of <a href="http://jakarta.apache.org/commons/jelly/">jelly</a>
+        as well.
+      </p>
+      <p>
+        To use your own templates, override the <code>maven.nsis.project.template</code>
+        and <code>maven.nsis.setup.template</code> variables.
+      </p>
+      <p>
+        The templates are expected to be well formed Jelly scripts, i.e. valid
+        XML documents.
+      </p>
+      <p>
+        If you do provide your own templates, you have complete control over
+        the way the installation process will work. You will also be able to
+        completely ruin it as well :-).
