Summarise a Tabletop RPG Sourcebook Into the Rules You Actually Need First

The sourcebook is enormous and reading it cover to cover before session one is not realistic for anyone with a life outside the hobby. This sorts the contents into what you genuinely need before your first session and what can safely wait, so the essentials fit in one sitting.

Paste in the table of contents or chapter summaries from a tabletop RPG sourcebook below. Summarise it into the essential rules a new player or game master needs before their first session, separated clearly from optional or advanced content that can wait until later. Keep the essentials section short enough to read in one sitting.
