Drop this script on your page and it will build you a beautiful widget that displays the status of your GitHub repo.
Everwhere you want a widget to be placed, add the following markup:
<div class="github-widget" data-repo="JoelSutherland/GitHub-jQuery-Repo-Widget"></div>
Then include the javascript file somewhere after you've include jQuery:
<script type="text/javascript" src="jquery.githubRepoWidget.min.js"></script>
That's it! All of the styling is included and image assets are pulled from GitHub.
