+=============================
+
+We've also made a `cookiecutter <http://cookiecutter.readthedocs.org/>`_
+project template for `creating new Mopidy extensions
+<https://github.com/mopidy/cookiecutter-mopidy-ext>`_. If you install
+cookiecutter and run a single command, you're asked a few questions about the
+name of your extension, etc. This is used to create a folder structure similar
+to the above, with all the needed files and most of the details filled in for
+you. This saves you a lot of tedious work and copy-pasting from this howto. See
+the readme of `cookiecutter-mopidy-ext
