In reply to Alexander.

Hey Alexander, this should apply to pretty much any theme:

In your WordPress Admin, go to Appearance > Widgets

There should be a Footer sidebar (or multiple if multiple columns) on the right-hand side. Drap and drop whichever widgets you like and want in your footer. Depending on your theme, you may be able to modify the amount of Footer columns in

Appearance > Theme Options

Let me know if you run into any other issues. Thanks!
