How do you upload images to a gist?

1. Create a gist or reuse one of your gists.
2. Clone your gist:

git clone https://gist.github.com/<hash>.git

3. Add your image to your gist's repository:

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.
