Whether you're trying to give back to the open source community or collaborating on your own projects, knowing how to properly fork and generate pull requests is essential. Unfortunately, it's quite easy to make mistakes or not know what you should do when you're initially learning the process. I know that I certainly had considerable initial trouble with it, and I found a lot of the information on GitHub and around the internet to be rather piecemeal and incomplete - part of the process described here, another there, common hangups in a different place, and so on.

In an attempt to coallate this information for myself and others, this short tutorial is what I've found to be fairly standard procedure for creating a fork, doing your work, issuing a pull request, and merging that pull request back into the original project.

Revert / Undo a Gist Commit

It was not exactly obvious. Here's how to revert a Gist commit!

Checkout the gist like a normal git repo:

# replace the Gist ID with your own
git clone [email protected]:cc13e0fcf2c348cc126f918e4a3917eb.git

Treat it like a normal repo. Edit, force push, etc.
