 This is just one way of doing things. If you're proficient in Git matters you're free to choose your own. If you want to read more then the [GitHub chapter in the Git book](http://git-scm.com/book/en/v2/GitHub-Contributing-to-a-Project#The-GitHub-Flow) is a way to start. [GitHub's own documentation](https://help.github.com/categories/collaborating-with-issues-and-pull-requests/) contains a wealth of information as well.
