I didnt expect much for the money, and I didnt get it. At just over 80 pages its the thinnest pocket guide I have bought to date. Some of its very basic, how to add comments, opening and closing tags, if you cant remember this then this book wont save you! It does go on to cover more useful stuff, like bean directives which I seem to forget now and then. Just about worth the money, not sure how much practical use it will be.
