How to Fix a Bug?

I’m new to the openSUSE Build Service and I am interested in starting with some of the junior jobs. However, I’ve never used Bugzilla before and am a little unfamiliar with the interface.

Once I’ve identified a bug that I’d be able to fix, what’s my next step? I’ve read the “How to fix a bug” section on the Junior Jobs page but I don’t understand what “osc” or “quilt” is.

When you start working on a bug, you can set yourself as assignee in bugzilla.

osc is the command line interface for the buildservice (openSUSE:OSC - openSUSE) and quild is a tool to manage patches for packages.
