+
+The theme plugin allows easily applying a theme to your wiki, by
+configuring the `theme` setting in the setup file with the name of a theme
+to use. The themes you can choose from are all subdirectories, typically
+inside `/usr/share/ikiwiki/themes/`.
+
+A theme provides, via the underlay, an enhanced version of the regular
+[[style.css]]. This leaves [[local.css]] free for you to further
+customise. Themes can also provide header and background images.
