Font Awesome Buttons

Buttons are not actually part of Font Awesome. What they are demonstrating on that page is Bootstrap buttons, but using Font Awesome icons inside of them. So if you have Bootstrap, or your theme supports buttons, you can use Font Awesome icons inside them.

For example, I’m using a WooTheme on my blog and I’ve put a Font Awesome icon inside a button provided by the theme (see the download link at the bottom of the page): http://blog.webguysaz.com/font-awesome-more-icons-wordpress-plugin/

Let me know if you still need help or more clarification.
