+Custom 404 pages 
+----------------
+
+GitHub Pages has a way to display a predefined custom 404 page when people try to 
+access nonexistent pages on your site. You can find more information about it 
+`here <https://help.github.com/articles/custom-404-pages/>`_. 
+
+The way to achieve this with Pelican would be to save a page as either ``404.md`` 
+or ``404.html``. The latter can be done by setting the ``save_as`` metadata. In 
+addition you should set ``status`` to ``hidden`` as well.
