This is a quick overview of how to set up a free personal website using GitHub.io. The only requirement is that you have a free GitHub account so that you can create a new repo.
Note: There is one mistake in the video. Once you've created a website, you CAN go back and edit it using markdown. Just click the settings button for the repo, and the click on the "Automatic Page Generator" link.
