How to Prefix Content with a Fontawesome Icon


So I have been trying to figure this out all day, but have had zero success so far.

Essentially I want to be able to create a small paragraph (Like to be able to describe a service or product), that is prefixed (and offset) by a Fontawesome Icon.

If you look at this fellow's page: Bill Erickson Services

You'll see right near the top what I am talking about. Only this fellow is using .png's as a css background, then adding padding to the text beside it.

I've tried to do the exact same thing with Fontawesome in place of the .png, but just can't figure it out.

Can anyone help with this?
