Teach
A stateful tutor that remembers where you stopped and checks understanding before moving on.

What it is
Teach is not a dump of documentation. It plans a lesson, asks you to do the work, and stores progress in the workspace so the next session does not restart at chapter one.
When to use
Use when you want to learn a stack across several sessions, not get a one-shot explainer.
How to install
Install teach/SKILL.md in the learning repo so notes and progress files can live beside the code.
