lol. Funny man. I'm not that good. I just drive around the internet looking for things I think I can work with. Check out this on CodePen. He is using fontawesome in his code, but I think it will give you some inspiration.

This can give you a general idea of how to use your own icons.

Of course you would place the html between the footer tags in the general index html file. If you want fontawesome capability, you can place the CDN in the html document file. You may have to play with the css styles a little for positioning, and possible some small adjustment on the foote, but it all depends.

I've attached what the CodePen looks like. Fortunately for me my themes are fontawesome ready. I took the css out that wasn't needed, and the div for the text header.
