I have created GitHub private repository and I added one collaborator to my private repository. I have created project at my computer with GitBash and pushed data to my GitHub Account. I would like to give the same thing to my collaborator user also, how can I do that, so that he can push data to my project. Then I can check updated Project Code. He can do this push from his project folder using GitBash or he can use Eclipse (like Android, PHP etc codes) to push. I would like to see the scenario like checkin and checkout as in VSS.
