Hi, Thanks for showing interest in OpenStack and really sorry for late response.

We have First Contact SIG now to help new contributors - https://wiki.openstack.org/wiki/First_Contact_SIG (https://wiki.openstack.org/wiki/First...)

Or ping any of member on #openstack-dev IRC channel. - Info on IRC channel here - https://wiki.openstack.org/wiki/IRC

If you have your interested project to start we have project liaison who can help and mentor you to start.

Otherwise i will say to start understanding any software, starting from its testing is easy way to understand that. OpenStack QA does responsible for testing and stability of OpenStack. If you are interested in QA, you can find more information on this wiki- https://wiki.openstack.org/wiki/QA Or ping core team (or me with irc name gmann) on #openstack-qa IRC channel.
