Adding Footer Link to old Genesis theme


On our website we have an out dated footer link that needs updated. When we built this a long time ago, Genesis made you copy and paste a piece of code into the theme file that enabled you to customize the included footer text. I cant remember where that is or how to do this. Can you suggest a method for updating the copyright to 2015 and for making the link point to and the anchor text to say Web Design by E3 Media? Thank you very much.
