Open source tree, there should be a “+Add” or “Add existing repository”.
Click it and it asks for the path of the existing Git-Repo on your hard drive, this way you should be able to connect both
Thank you, I finally managed to do it going to “Remote” (Cloud icon) and “Add an account…”. The pop up ask you for your GitHub data and clicking in “Refresh” button made appear my Battle Tank project ready to clone.
