+Generator Types
+---------------
+
 Python's :term:`generator`\s provide a convenient way to implement the iterator
 protocol.  If a container object's :meth:`__iter__` method is implemented as a
 generator, it will automatically return an iterator object (technically, a
 generator object) supplying the :meth:`__iter__` and :meth:`__next__` methods.
+More information about generators can be found in :ref:`the documentation for
+the yield expression <yieldexpr>`.
