You define the plug-in with the shortcode <code>list-github-repositories</code>. Don’t forget to define the user whose plug-ins you want to display, else you’ll get mine.
Afterwards you get a nice list with your repositories.
Similarly you can use a shortcode like <code>[show-github-repository user="slothsoft" repository="wordpress-github-repositories"]</code> to show a single repository’s HTML. GitHub parses the HTML itself, so you don’t need to fear unsupported markup.

GitHub Repositories

Just a silly project to see if I can create WordPress plug-ins. It displays a list of GitHub repositories or the README.md of a single repository.
