+Asset management plugin for Pelican
+===================================
+
+This plugin allows you to use the `webassets`_ module to manage assets such as
+CSS and JS files.
+
+The ASSET_URL is set to a relative url to honor Pelican's RELATIVE_URLS
+setting. This requires the use of SITEURL in the templates::
+
+    <link rel="stylesheet" href="{{ SITEURL }}/{{ ASSET_URL }}">
+
+.. _webassets: https://webassets.readthedocs.org/
