Errata and feedback

Reading feedback

If an explanation is hard to follow, an example needs another step, or a diagram is unclear, open a reader feedback issue. Include the page and the passage where you lost the thread. You do not need to propose a correction. Feedback in English or Chinese is welcome.

Report an error

For a factual, technical, translation, code, link, or accessibility problem, open an erratum issue.

Include the page URL, location, current content, and a proposed correction if you have one. Confirmed corrections will be recorded in the changelog.
