[ovirt-users] Can I get a way to commit ovirt Project?

Hello, I have been used to OLV/RHEV product about 3 years I often visit our community to get the error solution as well now I would try to use ovirt and develop to improve some function.. I'm using test environment using compiled oVirt 4.5 package. but I havent yet set up build develpment environment 1. Can you share and advise your ovirt development environment experience? 2. ovirt has some project, and how merge it to compile one source? 3. Is there a process for sharing what features you want to fix before making improvements? Can I just do PR? 4. your tips.. how to debug, ..etc
