How do I get "Quickly" to use Git?
Solution 1:
Unfortunately, in the current state of Quickly, you cannot. However it maybe possible to have Quickly extended to support this in the future, and you could report a bug.
I would caution against it though, since Quickly is not designed to use git, as it's really a tool for making it easier to use the Ubuntu related tools and environment to build Applications for Ubuntu (and possibly other Linux/UNIX systems if you choose to port the applications later). These tools would include Launchpad, Bazaar, etc.
