+## template files
+
+Template files are unlike template pages in that they have the extension
+`.tmpl`. Template files are used extensively by Ikiwiki to generate html.
+They can contain html that would not normally be allowed on a wiki page.
+
+Template files are located in `/usr/share/ikiwiki/templates` by default;
+the `templatedir` setting can be used to make another directory be
+searched first. Customised template files can also be placed inside the
+"templates/" directory in your wiki's source -- files placed there override
+ones in the `templatedir`.
