+Hackage package derivations are found in the
+[`hackage-packages.nix`](https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/haskell-modules/hackage-packages.nix)
+file within `nixpkgs` and are used as the initial package set for

+by hand, but rather autogenerated by [`hackage2nix`](https://github.com/NixOS/cabal2nix/tree/master/hackage2nix),
+which by default uses the [`configuration-hackage2nix.yaml`](https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/haskell-modules/configuration-hackage2nix.yaml)
+file to generate all the derivations.

+<para>The expression generates the needed
+configuration and writes it into your <literal>/etc/zshrc</literal>.

+
+<para>Sometimes third-party or custom scripts such as a modified theme may be needed.
+<literal>oh-my-zsh</literal> provides the
+<link xlink:href="https://github.com/robbyrussell/oh-my-zsh/wiki/Customization#overriding-internals"><literal>ZSH_CUSTOM</literal></link> 
+environment variable for this which points to a directory with additional scripts.</para>
+
+<para>The module can do this as well:
+
+<programlisting>
+{
+  programs.ohMyZsh.custom = "~/path/to/custom/scripts";
+}
+</programlisting>
+</para></section>
+
+<section><title>Custom environments</title>

+<para>There are several extensions for <literal>oh-my-zsh</literal> packaged in <literal>nixpkgs</literal>.
+One of them is <link xlink:href="https://github.com/spwhitt/nix-zsh-completions">nix-zsh-completions</link>
+which bundles completion scripts and a plugin for <literal>oh-my-zsh</literal>.</para>
+
+<para>Rather than using a single mutable path for <literal>ZSH_CUSTOM</literal>, it's also possible to

+    <para>To comply with the default structure of <literal>ZSH</literal> the entire output needs to be written to

+  <listitem>
+    <para>Completion scripts are supposed to be stored at <literal>$out/share/zsh/site-functions</literal>. This directory
+    is part of the <literal><link xlink:href="http://zsh.sourceforge.net/Doc/Release/Functions.html">fpath</link></literal>
+    and the package should be compatible with pure <literal>ZSH</literal> setups. The module will automatically link
+    the contents of <literal>site-functions</literal> to completions directory in the proper store path.</para>
+  </listitem>
+  <listitem>
+    <para>The <literal>plugins</literal> directory needs the structure <literal>pluginname/pluginname.plugin.zsh</literal>
+    as structured in the <link xlink:href="https://github.com/robbyrussell/oh-my-zsh/tree/91b771914bc7c43dd7c7a43b586c5de2c225ceb7/plugins">upstream repo.</link>
