Editing and sharing content with gists
You can create two kinds of gists: public and secret. Create a public gist if you're ready to share your ideas with the world or a secret gist if you're not.
Forking and cloning gists
Gists are actually Git repositories, which means that you can fork or clone any gist, even if you aren't the original author. You can also view a gist's full commit history, including diffs.
