Have a look at the table of contents and get an idea of just how far down the rabbit hole we're going to go. This book strives to be a balanced source of technical reference material, so each chapter should be able to stand on its own.
It wouldn't kill you to read the chapters in the order presented. However, feel free to jump around and sample what you like. There's more here than meets the eye. As a rule, the chapters go from the general to the specific. If you skip around a lot and get stranded, try backing up a chapter or two to make sure you have the proper grounding and then proceed forward again.
