We'll use a client called SourceTree.

Download SourceTree from: You can also follow along with the video tutorial to the right. We'll start this class with a code repository that has already been created. The code is currently hosted on a website callded “BitBucket.” Go to BitBucket and sign up: Once you have signed up, go to the code repository that I've created: The next step is to create your own copy of my repository so that you can change it however you like.
