Many parts it does jump too ahead, and it doesn't cover all of the commands and explain things in full detail. It basically shows examples of most commonly used commands. It has a lot of nice examples though, but you may want to read up on them first.
These files are quite helpful
Commands.rtf
newfeatures2001.txt
newfeatures2002.txt

Those can be found in the folder Graal2002.

I also attached the old npcprogramming.doc
