Your Team Has an Internal Onboarding Doc for Juniors? That's Already 80% of a Course

If you've ever onboarded a junior on your team, you probably have a doc — or three — sitting in Confluence, Notion, or some private repo, explaining how your team does code review, how to set up the dev environment, what mistakes to avoid, what your commit convention looks like. That knowledge lives in an internal wiki and never leaves it.

That's exactly the kind of material that turns into a course.

The gap between "internal doc" and "course" is smaller than it looks:

  • A text doc → a lesson with tables, code blocks, and Mermaid diagrams if you're explaining architecture or a data flow.
  • "Try setting this up and let me know how it goes" → a code challenge that actually checks whether the student can do it, run in a sandbox in one of 13 supported languages — no more "done ✅" on Slack, the result gets checked automatically.
  • Your three most-repeated pieces of code review feedback → a standalone lesson on the mistakes you always see from new hires.

You don't need to start from zero and invent a curriculum. The material already exists — it just needs to come out of the internal wiki, get organized, and turn into something someone outside the company can work through too.

Bonus: next time you hire a junior, you can send a link instead of explaining the same thing live all over again.

Set up an instructor account on cursora.org — see how much of what you already know and already have written down turns into a first lesson in under an hour.
