Link to the script in your code after you include the main Bootstrap JS file(s):
<script src="<...>/jquery.min.js"></script>
<script src="<...>/bootstrap.min.js"></script>
<script src="//cdn.rawgit.com/tonystar/bootstrap-hover-tabs/master/bootstrap-hover-tabs.js"></script>
That's it. No additional configuration required!
