Start with the development runbook. Setup lives in the root README; contribution policy is in CONTRIBUTING.md; agent rules are in AGENTS.md.
Internal notes preserve architectural decisions, constraints, and implementation traps that the source alone does not explain. Most code changes do not need an internal documentation update. Follow the documentation rules before adding one.
