+=head1 NAME
+
+ikiwiki Plug-in: h1title
+
+=head1 SYNOPSIS
+
+If there is a level 1 Markdown atx-style (hash mark) header on the first line,
+this plugin uses it to set the page title and removes it from the page body so
+that it won't be rendered twice.  Level 1 headers in the remainder of the page
+will be ignored.
+
+For example, the following page will have title "My Title" and the rendered
+page body will begin with the level two header "Introduction."
+
+    # My Title
+
+    ## Introduction
+    
+    Introductory text with a list:
+    
+     * Item 1
+     * Item 2
+
+    ## Second header
+
+    Second section
+
+This plugin can be used with page templates that use <h1> tags for the page
+title to produce a consistent header hierarchy in rendered pages while keeping
+the Markdown source clean and free of meta directives.
