+<h3>Customisation</h3>
+<p>
+To customise keybindings, you can just use zsh's bindkey utility. However, if
+you plan to to use the `<i>zle-line-init</i>' or `<i>zle-line-finish</i>' hooks
+yourself, make sure you call the following functions in the respective hook:
+</p>
+<ul>
+<li><b>zle-line-init</b>: <i>zle-smkx</i>
+</li>
+<li><b>zle-line-finish</b>: <i>zle-rmkx</i>
+</li>
+</ul>
+<p>
+This is <b>required</b> so the keybindings set up by <i>grmlzshrc</i> work. The
+reason for this is to turn the terminal into the right mode while zsh's line
+editor (zle) is running. This enables us to query <i>terminfo</i> about escape
+sequences for special keys and thus simplify and generalise our keybinding
+section.
