If you know how to make good maps, but not have an idea on how parallax mapping works, then this tutorial is for you. It doesn't show how to make great maps, that has been shown well already by other tutorials here and there. But I found out that it was somewhat intimmidatating for me to set a project up to use Parallaxed maps. When I made it, I found out that things are VERY simple. If you want to use bigger maps than a certain dimension, you will just have to use a few scripts. Works the same it just becomes a little more complicated.
