+ <para>
+  In some cases, it may be desirable to take advantage of commonly-used,
+  predefined configurations provided by nixpkgs, but different from those that
+  come as default. This is a role fulfilled by NixOS's Profiles, which come as
+  files living in <filename>&lt;nixpkgs/nixos/modules/profiles&gt;</filename>.
+  That is to say, expected usage is to add them to the imports list of your
+  <filename>/etc/configuration.nix</filename> as such:
+ </para>
+ <programlisting>
+  imports = [
+   &lt;nixpkgs/nixos/modules/profiles/profile-name.nix&gt;
+  ];
+ </programlisting>
+ <para>
+  Even if some of these profiles seem only useful in the context of
+  install media, many are actually intended to be used in real installs.
+ </para>
+ <para>
+  What follows is a brief explanation on the purpose and use-case for each
+  profile. Detailing each option configured by each one is out of scope.
