Hello
We have no tutorial at the moment however it is pretty self explanatory. The module uses Font Awesome to create the icons (
http://fortawesome.github.io/Font-Awesome/3.2.1/icons/). Simply add the class name of Font Awesome icon you wish to appear (eg. fa-coffee) to the 'Font Awesome Icon' field. A field also exists for the description and link. You can use the 'General Settings' tab to style the icons to your own taste.
