+    <title>Cthulhu Preferences</title>
+    <p>
+      Cthulhu preferences allow you to customize functionality in <app>Cthulhu</app>
+      which applies to all applications. An example of an Cthulhu preference is
+      echo because echo is something that applies to all applications.
+    </p>
+    <p>
+      Note that Cthulhu preferences can be customized on an application-by-application
+      basis. For instance you can set the default echo to words and then
+      set the echo for Pidgin to be none. Having done so, <app>Cthulhu</app>
+      would always echo each word that you typed, unless you were in Pidgin.

+      <p>
+        In contrast to Cthulhu preferences, there are application-unique preferences.
+        These preferences allow you to customize <app>Cthulhu</app> functionality
+        that only applies in certain environments, such as on web pages or in
+        chat applications. As a result, you will only find these options
+        available in the application-specific preferences dialogs and only for
+        those applications to which these options apply.
