If you would like to contribute to the development of OpenStack, you must follow the steps in this page: [http://docs.openstack.org/infra/manual/developers.html](http://docs.openstack.org/infra/manual/developers.html#development-workflow) Once those steps have been completed, changes to OpenStack should be submitted for review via the Gerrit tool, following the workflow documented at [http://docs.openstack.org/infra/manual/developers.html#development-workflow](http://docs.openstack.org/infra/manual/developers.html#development-workflow). Pull requests submitted through GitHub will be ignored. Bugs should be filed [on Launchpad](https://bugs.launchpad.net/cinder), not in GitHub's issue tracker.
