To be honest, I've only found about 1% of extensions for Joomla 3.x to be useful, and this extension is in the 1%. It's straightforward to use, does not contain a bunch of convoluted explanation, and simply provides the necessary files/paths in Joomla for you to be able to seamlessly incorporate the latest FontAwesome fonts anywhere in your design. I'm using it in bootstrap buttons, etc. Very easy to consult the FontAwesome website for the correct syntax to use in the class for exacting results. Trying to incorporate IcoMoon fonts and other font icon libraries into my custom templates was a pain, but this extension made using FontAwesome a breeze for my Joomla 3.2.x installation. "Thank you, thank you" to the developer.
