-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 large-scale.
-
-Communication
-~~~~~~~~~~~~~
-.. This would be a good place to put the channel you chat in as a project; when/
-   where your meeting is, the tags you prepend to your ML threads, etc.
-
-Contacting the Core Team
-~~~~~~~~~~~~~~~~~~~~~~~~
-.. This section should list the core team, their irc nicks, emails, timezones
-   etc. If all this info is maintained elsewhere (i.e. a wiki), you can link to
-   that instead of enumerating everyone here.
-
-New Feature Planning
-~~~~~~~~~~~~~~~~~~~~
-.. This section is for talking about the process to get a new feature in. Some
-   projects use blueprints, some want specs, some want both! Some projects
-   stick to a strict schedule when selecting what new features will be reviewed
-   for a release.
-
-Getting Your Patch Merged
-~~~~~~~~~~~~~~~~~~~~~~~~~
-.. This section should have info about what it takes to get something merged. Do
-   you require one or two +2's before +W? Do some of your repos require unit
-   test changes with all patches? etc.
-
-Project Team Lead Duties
-~~~~~~~~~~~~~~~~~~~~~~~~
-.. this section is where you can put PTL specific duties not already listed in
-   the common PTL guide (linked below), or if you already have them written
-   up elsewhere you can link to that doc here.
-
-All common PTL duties are enumerated in the `PTL guide
-<https://docs.openstack.org/project-team-guide/ptl.html>`_.
