How to move to a fork after cloning
View gist:710671
So you've cloned somebody's repo from github, but now you want to fork it and contribute back. Never fear!
Technically, when you fork "origin" should be your fork and "upstream" should be the project you forked; however, if you're willing to break this convention then it's easy.
* Off the top of my head *
1. Fork their repo on Github
2. In your local, add a new remote to your fork; then fetch it, and push your changes up to it
git remote add my-fork git@github...my-fork.git
You can’t perform that action at this time.
