Creating a pull request with GitHub Desktop

I was asked to create this. Bear with me, as I normally use a very different environment to develop with. Questions welcome, and I'll clarify as I go.

The main gist of creating a pull request goes like this:

1. Fork this repo.
2. On your fork, create a branch for the changes you want to make to go into.
3. Make your changes, commit them to your branch.
4. Open a PR on GitHub from your branch, to this main repo.

I've gone through the process above in a visual guide here:
