Contact
There is no contact form on this page, and that is not an oversight. This site has no backend to receive one — so everything goes through the repository instead, where it is public, tracked, and next to the file that would have to change.
Something in a lesson is wrong
Open an issue and name the lesson. Errors about SDK versions, deprecated APIs and prices that have moved are the most useful kind of report there is — this material dates quickly, and it dates quietly.
Open an issueYou want a topic covered
Eight of the nine courses are outlines waiting to be written, so the order they get written in is genuinely open. An issue saying which one you would use, and what you need it to answer, is the thing most likely to move it up.
You would rather just fix it
Lessons are MDX files and the curriculum is a TypeScript manifest; both are in the repository, alongside the notes describing how a lesson is assembled. Pull requests are welcome.
