No, there was no tutorial. first I had to install funplug. Then through its package manager I've added ssh (there is a tutorial for that) and git. Now git works over ssh. I cannot use the git protocol nor git-shell. But for a small project (for me) it was just enough. It looks like as a local git repo that is accessed through ssh. No hooks no user management. (All ssh-user can access the git)
As I remember installing funplug and changing the permission of etc was the hard part.
