How To Add Parallax Mapping/Steep Parallax Maps?

Hey guys, I’m very familiar with normal maps and how to use them because I use them a lot in my games. I recently stumbled over “Parallax Mapping” though. It looks like it adds a ton more detail than normal maps. The only issue is how do I use it in blender? I know blender supports Parallax Maps because it says it does on the blender.org website under features and Game engine.

How to I add this? And how do I add Steep Parallax mapping, because Steep Parallax mapping seems as if it would add a hell of a lot of detail to my games and I am dying to be able to use this in my games.

-Thanks
