# Course website

Astro Starlight site built from the lessons in `course/`.

Run locally: `npm ci && npm run dev` (from this directory), then open http://localhost:4321.

`COURSE_HOST` (e.g. `course.example.com`) sets the public site URL at build time. Unset, the site uses `http://localhost:4321`. Deploys must set it; see `../deploy/README.md`.
