If you would like to contribute to the development of OpenStack, you must follow the steps in the "If you're a developer, start here" section of this page:
http://wiki.openstack.org/HowToContribute
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
Pull requests submitted through GitHub will be ignored.
Bugs should be filed on Launchpad, not GitHub:
