It is an improvement on the documentation that comes from Linksys, but I was disappointed. It could have had a few more pictures, and I was expecting detailed explanations on how to configure all features of a router. When I got to the VPN portion of the book, which I was particularly interested in, it said, "See a consultant." Needless to say, that wasn't exactly what I was hoping for. But if you're just getting started, it will probably help you.
