The CG aims for a degree of completeness. Naturally, a set of rules for writing good code in general cannot be complete, but the necessary degree of completeness implies that the CG are not meant for a systematic read. I recommend the introduction and the philosophy section to get an impression of the aims of the CG and its conceptual framework. However, for a selective tour of the CG guided by taste, perspective, and experience, read the book. For true geeks, it is an easy and entertaining read. For most software developers, it offers something new and useful.
