Tell us what is broken, confusing, or missing

A lesson that did not land is useful feedback. So is a typo, an outdated API, or a community problem. Pick the route that fits.

Send a private message

This form is for messages that should not be public: account requests, conduct reports, security details, or feedback you would rather not post.

Ask under the lesson itself. The answer stays searchable for the next learner, which a private email does not.

A public issue is best for reproducible bugs: include the page, expected result, actual result, and browser. Do not paste secrets or personal data.

Do not disclose a vulnerability in a public issue. Use the repository's private security reporting tab and include reproduction steps and impact.

Share a project, leave feedback, or read the rules for every community space.

Replies are best effort, usually within a week. This is a free project, not a support desk or a one-to-one tutoring service.
