This section holds the policies and templates that govern contributions to docs.optimism.io. Each page is a contract: reviewers cite its sections in docs PRs instead of re-arguing them, so read the pages that match what you are about to write. Find the canonical home for what you want to write, and what stays out of the docs entirely. Match the voice, tone, formatting, and naming conventions every page follows. Use the decision table to choose a content type, then follow its published contract and template. Write cross-repo links in the canonical form the link linter enforces. Follow the review cadence, the last-reviewed contract, and the rule for delisting content that rots. Build a new component's identity page against the uniform hub skeleton. Propose changes to the "Learn the OP Stack" track through its governance artifact. Browse the documentation by role: app developer, chain operator, or node operator.
