It goes into allot of detail, and attempts to show lots of different methods how to use this brilliant price of software. It is a big book and I mean BIG, and will take some time to go through it all, but the suggestions of what you can or need to do with this program from start to finish is very good. Plenty of tutorials with videos for ref online that Martin has put together, and examples to follow along with. Think of this book as a strong reference guide, and use for times when your unsure of what a particular tool does and how you use it. Well worth the money which isn't a great deal, so buy it folks.
