.. |draft| replace::
    This is part of a **Draft** of the Python Contributor's Guide.
    Text in square brackets are notes about content to fill in.
    Currently, the devguide and this new Contributor's Guide co-exist in the
    repo. We are using Sphinx include directives to demonstrate the re-organization.
    The final Contributor's Guide will replace the devguide with content in only one
    place.
    We welcome help with this!

.. |purpose| replace::
    The :ref:`contrib-plan` page has more details about the current state of this draft
    and **how you can help**.  See more info about the Contributor Guide in the
