It lists approved game terms and references, explains how to use related forms, and provides blank formatting templates for original monster, poison, skill challenge, and similar statistics. The guidelines describe how to develop compatible content while avoiding reproduction or alteration of rules text, statistics, tables, and protected definitions from the core rulebooks.
