+============================
+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 OpenStack-Ansible.
+
+Communication
+~~~~~~~~~~~~~
+
+IRC channel
+^^^^^^^^^^^
+
+The OpenStack-Ansible community communicates in the #openstack-ansible IRC
+channel hosted on freenode. This channel is logged, and its logs are published
+on http://eavesdrop.openstack.org/irclogs/%23openstack-ansible/.
+
+Weekly meetings are held in our IRC channel. The schedule and
+logs can be found on
+http://eavesdrop.openstack.org/#OpenStack_Ansible_Deployment_Meeting.
+The agenda for the next meeting can be found on our
+`Meetings wiki page <https://wiki.openstack.org/wiki/Meetings/openstack-ansible>`_.
+
+Mailing lists
+^^^^^^^^^^^^^
+
+Members of the OpenStack-Ansible community should monitor the
+**OpenStack-discuss** `mailing lists`_.
+
+.. _mailing lists: http://lists.openstack.org/cgi-bin/mailman/listinfo
+
+All our communications should be prefixed with **[openstack-ansible]**.
+
+Contacting the Core Team
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+All of our core team is available through IRC and present in #openstack-ansible
+channel on Freenode. The list of the current members of the OpenStack-Ansible Team
+might be found on `gerrit`_.
+
+.. _gerrit: https://review.opendev.org/#/admin/groups/490,members
+
+
+New Feature Planning
+~~~~~~~~~~~~~~~~~~~~
+
+If you would like to contribute towards a role to introduce an OpenStack
+or infrastructure service, or to improve an existing role, the
+OpenStack-Ansible project would welcome that contribution and your assistance
+in maintaining it.
+
+Please look through :dev_docs:`Contributor Guidelines <contributor/contribute.html>`
+page for more information about the process.
+
+
+Task Tracking
+~~~~~~~~~~~~~
+
+We track our tasks in Launchpad
+
+   https://bugs.launchpad.net/openstack-ansible
+
+
+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
+`Launchpad
+<https://bugs.launchpad.net/openstack-ansible>`_.

+
+Also you may find more detailed information about how to work with bugs
+on the page :dev_docs:`Bug Handling <contributor/bugs.html>`
+
+
+Getting Your Patch Merged
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Any new code will be reviewed before merging into our repositories and
+requires at least 2 approvals from our Core team.
+
+We follow openstack guidelines for the `code reviewing <https://docs.openstack.org/project-team-guide/review-the-openstack-way.html>`_ process.
+
+Please be aware that any patch can be refused by the community if they
+don't match the :ref:`codeguidelines`.
