+
+This plugin allows registering template pages, that provide default
+content for new pages created using the web frontend. To register a
+template, insert a [[PreprocessorDirective]] on some other page.
+
+	\[[edittemplate template="bugtemplate" match="bugs/*"]]
+
+In the above example, the page named "bugtemplate" is registered as a
+template to be used when any page named "bugs/*" is created.
+
+[[template id=note text="""
+Note: It's generally not a good idea to put the `edittemplate` directive in
+the template page itself, since the directive would then be included as
+part of the template on new pages, which would then in turn be registered
+as templates. If multiple pages are registered as templates for a new page,
+an arbitrary one is chosen, so that could get confusing.

+
+Often the template page contains a simple skeleton for a particular type of
+page. For the bug report pages in the above example, it might look
+something like:
+
+	Package: 
+	Version: 
+	Reproducible: y/n
+	Details:
+
+The template page can also contain [[cpan HTML::Template]] directives,
+similar to other ikiwiki [[templates]]. Currently only one variable is
+set: `<TMPL_VAR name>` is replaced with the name of the page being
+created.
