+Pelican ``headerid`` plugin
+===========================
+
+This plugin adds an anchor to each heading so you can deep-link to headers.
+It is intended for formats such as reStructuredText that do not natively
+generate these anchors.
+
+The ``HEADERID_LINK_CHAR`` config can be set to use a different char from ``*``
+for anchor text.
+
+For Markdown, this plugin is less relevant since the Python-Markdown library
+includes a Table of Contents extension that will generate link anchors.
+To enable the ``toc`` extension, add a line similar to the following example
+to your Pelican settings file::
+
+    MD_EXTENSIONS = ["codehilite(css_class=highlight)", "extra", "toc"]
