+      recursive-include django_polls/templates *
 
 #. It's optional, but recommended, to include detailed documentation with your
    app. Create an empty directory ``django-polls/docs`` for future
-   documentation. Add an additional line to ``django-polls/MANIFEST.in``:
-
-   .. code-block:: text
-
-      recursive-include docs *
+   documentation.
 
    Note that the ``docs`` directory won't be included in your package unless
    you add some files to it. Many Django apps also provide their documentation
    online through sites like `readthedocs.org <https://readthedocs.org>`_.
