+============================
+So You Want to Contribute...
+============================
+For general information on contributing to OpenStack, please check out the
+`contributor guide <https://docs.openstack.org/contributors/>`_ to get started.
+It covers all the basics that are common to all OpenStack projects: the accounts
+you need, the basics of interacting with our Gerrit review system, how we
+communicate as a community, etc.
+Below will cover the more project specific information you need to get started
+with python-cloudkittyclient.
+
+Communication
+~~~~~~~~~~~~~
+* IRC channel #cloudkitty at `OFTC <http://oftc.net>`_
+* Mailing list (prefix subjects with ``[cloudkitty]`` for faster responses)
+  http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-discuss
+
+Contacting the Core Team
+~~~~~~~~~~~~~~~~~~~~~~~~
+Please refer the `python-cloudkittyclient Core Team
+<https://review.opendev.org/admin/groups/4ac765c35f985b3ad9226da07fdcc205c1ce4fe1,members>`_ contacts.
+
+New Feature Planning
+~~~~~~~~~~~~~~~~~~~~
+Cloudkitty features are tracked on `Storyboard <https://storyboard.openstack.org/#!/project/895>`_.
+
+Task Tracking
+~~~~~~~~~~~~~
+We track our tasks in `Storyboard <https://storyboard.openstack.org/#!/project/895>`_.
+If you're looking for some smaller, easier work item to pick up and get started
+on, search for the 'low-hanging-fruit' tag.
+
+Reporting a Bug
+~~~~~~~~~~~~~~~
+You found an issue and want to make sure we are aware of it? You can do so on
+`StoryBoard <https://storyboard.openstack.org/#!/project/895>`_.
+
+Getting Your Patch Merged
+~~~~~~~~~~~~~~~~~~~~~~~~~
+All changes proposed to the python-cloudkittyclient project require one or two +2 votes
+from python-cloudkittyclient core reviewers before one of the core reviewers can approve
+patch by giving ``Workflow +1`` vote.
+
+Project Team Lead Duties
+~~~~~~~~~~~~~~~~~~~~~~~~
+All common PTL duties are enumerated in the `PTL guide
+<https://docs.openstack.org/project-team-guide/ptl.html>`_.
