If you would like to contribute to the development of OpenStack, you must follow the steps in the "If you're a developer" section of this page: [http://wiki.openstack.org/HowToContribute](https://wiki.openstack.org/HowToContribute#If_you.27re_a_developer) Once those steps have been completed, changes to OpenStack should be submitted for review via the Gerrit tool, following the workflow documented at [http://wiki.openstack.org/GerritWorkflow](https://wiki.openstack.org/GerritWorkflow). 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.
