 How do I...
 -----------
 
+... customize the look of the built HTML files?
+   Use themes, see :doc:`theming`.
+
 ... add global substitutions?
    Add them in the :confval:`rst_epilog` config value.
 
+... write my own extension?
+   See the :ref:`extension tutorial <exttut>`.
+   
 ... use Sphinx with Epydoc?
    There's a third-party extension providing an `api role`_ which refers to
    Epydoc's API docs for a given identifier.
