Most projects on GitHub use the master branch as the development branch. That means when users wants to view docs for the version of the project they’re using, they need to go to the correct Git tag, since the master branch might document unreleased features. We added a button to the project readme to quickly go to the readme of the latest release.

I recently had this issue with Prettier and node_modules ignoring. I was going to create my own plugin just to do this, now I don’t have to! :D Best feature IMO, reading the docs equal to the latest release should be default in GitHub unless you’re a contributor. Thanks for this!
