+Ikiwiki uses the HTML::Template module as its template engine. This
+supports things like conditionals and loops in templates and is pretty
+easy to learn. All you really need to know to modify templates is this:
-* `templates/page.tmpl` - Used for displaying all regular wiki pages.
-* `templates/recentchanges.tmpl` - Used for the RecentChanges page.
-* `templates/edit.tmpl' - Edit page.
-* `templates/create.tmpl' - Creating a new page.
-* `templates/signin.tmpl` - Used for the SignIn form and all assciated forms, if it exists.
-
- Note that the SignIn form is implemented using CGI::FormBuilder, which interfaces to HTML::Template, so not all of it can be customised with templates, although most of it can, by creating this template. Without the template, CGI::FormBuilder creates the page by itself.
+* To insert the value of a template variable, use `<TMPL_VAR variable>`.
+* To make a block of text conditional on a variable being set use
+ `<TMPL_IF variable>text</TMPL_IF>`.
+* To use one block of text if a variable is set and a second if it's not,
+ use `<TMPL_IF variable>text<TMPL_ELSE>other text</TMPL_IF>`
-I aim to keep almost all html out of ikiwiki and in the templates.

+## 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`.
+
+Here is a full list of the template files used:
+
+* `page.tmpl` - Used for displaying all regular wiki pages. This is the
+ key template to customise to change the look and feel of Ikiwiki.
+ [[!if test="enabled(pagetemplate)" then="""
+ (The [[!iki ikiwiki/directive/pagetemplate desc="pagetemplate directive"]]
+ can be used to make a page use a different template than `page.tmpl`.)"""]]

+* `rssitem.tmpl` - Used for generating individual items on rss feeds.
+* `atompage.tmpl` - Used for generating atom feeds for blogs.
