Alright, article, reiterating what Bob Myers said: this article is not very handy in someone that wants to learn about Git Stashing. It also sounds like you don’t know what Git Stashing does outside of Fork.
In the future, I recommend writing about what the service is first. What does git-stash actually do (if you don’t know the API explains it thoroughly https://git-scm.com/docs/git-stash). After an overview, then break it down into the specifics. How to use Git Stash in Fork, GitKraken, GitHub Desktop, etc.
