GitHub has a variety of paid plans, but for open-source code their services are free, so sign up for a free GitHub account if you don’t have one already. (You might have to follow the GitHub tutorial on creating SSH keys first.) After signing up, click on the link to create a repository and fill in the information as in Figure 1.6.
