+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"]

+Sitemap
+-------
+
+This plugin generates plain-text or XML sitemaps. You can use the ``SITEMAP``
+variable in your settings file to configure the behavior of the plugin.
+
+The ``SITEMAP`` variable must be a Python dictionary and can contain these keys:
+
+- ``format``, which sets the output format of the plugin (``xml`` or ``txt``)
+
+- ``priorities``, which is a dictionary with three keys:
+
+  - ``articles``, the priority for the URLs of the articles and their
+    translations
+
+  - ``pages``, the priority for the URLs of the static pages
+
+  - ``indexes``, the priority for the URLs of the index pages, such as tags,
+     author pages, categories indexes, archives, etc...
+
+  All the values of this dictionary must be decimal numbers between ``0`` and ``1``.
+
+- ``changefreqs``, which is a dictionary with three items:
+
+  - ``articles``, the update frequency of the articles
+
+  - ``pages``, the update frequency of the pages
+
+  - ``indexes``, the update frequency of the index pages
+
+  Valid frequency values are ``always``, ``hourly``, ``daily``, ``weekly``, ``monthly``,
+  ``yearly`` and ``never``.
+
+You can exclude URLs from being included in the sitemap via regular expressions.
+For example, to exclude all URLs containing ``tag/`` or ``category/`` you can
+use the following ``SITEMAP`` setting.
+
+.. code-block:: python
+
+    SITEMAP = {
+        'exclude': ['tag/', 'category/']
+    }
+
+If a key is missing or a value is incorrect, it will be replaced with the
+default value.
+
+The sitemap is saved in ``<output_path>/sitemap.<format>``.
+
+.. note::
+   ``priorities`` and ``changefreqs`` are information for search engines.
+   They are only used in the XML sitemaps.
+   For more information: <http://www.sitemaps.org/protocol.html#xmlTagDefinitions>
+
+**Example**
+
+Here is an example configuration (it's also the default settings):
+
+.. code-block:: python
+
+    PLUGINS=['pelican.plugins.sitemap',]
+
+    SITEMAP = {
+        'format': 'xml',
+        'priorities': {
+            'articles': 0.5,
+            'indexes': 0.5,
+            'pages': 0.5
+        },
+        'changefreqs': {
+            'articles': 'monthly',
+            'indexes': 'daily',
+            'pages': 'monthly'
+        }
