-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.
-
-I aim to keep almost all html out of ikiwiki and in the templates.
-
-It ships with some basic templates which can be customised:
-
-* `templates/page.tmpl` - Used for displaying all regular wiki pages.
-* `templates/misc.tmpl` - Generic template used for any page that doesn't
-  have a custom template.
-* `templates/recentchanges.tmpl` - Used for the RecentChanges page.
-* `templates/editpage.tmpl` - Create/edit page.
-* `templates/passwordmail.tmpl` - Not a html template, this is used to
-  generate the mail with the user's password in it.
-* `templates/rsspage.tmpl` - Used for generating rss feeds for [[blog]]s.
-* `templates/inlinepage.tmpl - Used for adding a page inline in a blog
-  page.
-* `templates/inlinepagetitle.tmpl - Used for listing a page inline in a blog
-  archive page.
-
-If you like, you can add these to further customise it:
-
-* `templates/signin.tmpl` - If it exists, it is used for customising the
-  layout of the SignIn form and all assciated forms. The misc.tmpl is
-  wrapped around this, so it should only be a template for the form.
-* `templates/prefs.tmpl` - If it exists, it is used for customising the
-  layout of the Prefs form and all assciated forms. The misc.tmpl is
-  wrapped around this, so it should only be a template for the form.
-  
-Note that the SignIn and Prefs forms are 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 these
-templates. Without the templates, CGI::FormBuilder creates the page bodies
-by itself.

+Templates are files that can be filled out and inserted into pages in the
+wiki.
+
+[[if test="enabled(template) and enabled(inline)" then="""
+
+## Available templates
+
+These templates are available for inclusion onto other pages in this
+wiki:

+
+## Using a template
+
+Using a template works like this:
+
+	\[[template id=note text="""Here is the text to insert into my note."""]]
+
+This fills out the [[note]] template, filling in the `text` field with
+the specified value, and inserts the result into the page.
+
+A value can include any markup that would be allowed in the wiki page
+outside the template. Triple-quoting the value even allows quotes to be
+included in it. Combined with multi-line quoted values, this allows for
+large chunks of marked up text to be embedded into a template:
+
+        \[[template id=foo name="Sally" color="green" age=8 notes="""
+        * \[[Charley]]'s sister.
+        * "I want to be an astronaut when I grow up."
+        * Really 8 and a half.
+        """]]
+
+## Creating a template
+
+To create a template, simply add a template directive to a page, and page will
+provide a link that can be used to create the template. The template is a
+regular wiki page, located in the `templates/` directory.
+
+The template uses the syntax used by the
+[cpan HTML::Template](http://search.cpan.org/search?mode=dist&query=HTML::Template)
+perl module, which allows for some fairly complex things to be done.
+Consult its documentation for the full syntax, but all you really need to know
+are a few things:
+
+* To insert the value of a variable, use `<TMPL_VAR variable>`.
+* To make a block of text conditional on a variable being set use
+  `<TMPL_IF NAME="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 NAME="variable">text<TMPL_ELSE>other text</TMPL_IF>`
+
+Here's a sample template:
+
+        <span class="infobox">
+        Name: <TMPL_VAR name><br />
+        Age: <TMPL_VAR age><br />
+        <TMPL_IF NAME="color">
+        Favorite color: <TMPL_VAR color><br />
+        <TMPL_ELSE>
+        No favorite color.<br />
+        </TMPL_IF>
+        <TMPL_IF NAME="notes">
+        <hr />
+        <TMPL_VAR notes>
+        </TMPL_IF>
+        </span>
+
+The filled out template will be formatted the same as the rest of the page
+that contains it, so you can include WikiLinks and all other forms of wiki
+markup in the template. Note though that such WikiLinks will not show up as
+backlinks to the page that uses the template.
