Crytek Sandbox editor Tutorial?

[Per Hansson]

Hi, there is a tutorial for the Half-Life engine that I found great, just a simple help file which described from the ground up how to make a small room filled with stuff, just so you should learn how to use the editor...

I want to know if something similar exists for the Sandbox engine... The only thing I've found is this which is not very helpful when you are starting at a complete beginners stage...
