[Pharo-dev] Using Filetree w/ Git - docs?

I have been loading Filetree in a fresh image, created a sample package, a sample class, a sample method. The created a MCPackage and saved it into a filetree repository (which happens to be a folder on the machine, no problem). Now, how is one associating that with git? (and github or bitbucket). Should I do a normal git thing, creating the project etc from the command line (or using SourceTree, which happens to lower my level of Git headaches). Thanks for outlining the process. I need private repos and as we do use Atlassian Bitbucket/Jira/Confluence for the project, Filetree + Git is a great answer I'd like to have working. Thx! Phil
