+## Notes
+
+Course site for the laser cutting intro course ("Introkursus til lille laser"),
+in Danish. Serves the course materials (slides, plancher, worked examples) for
+download and takes participant file uploads during the course.
+
+Behind Traefik basicAuth — the credentials are handed out in class. Uploads are
+restricted to laser-relevant formats (SVG, DXF, PDF, common raster, archives),
+capped at 20 MB, and stored as `<participant>_<timestamp>_<filename>` under
+`/srv/laser_course/uploads`.
+
+Deployed from the `baobab.laser-course` role in AnsibleBaobabV4 (the app source
+and the course materials both live in that role):
+
+```bash
+ansible-playbook play_containers.yml --limit makerfloss -t laser-course
+```
+
+Two things worth knowing before a course:
+
+- **Uploads are not backed up.** `backup_enabled` is false on this VPS, and
+  `laser_course_clean_uploads_on_deploy` is set to false here so that an
+  unrelated deploy does not delete them. Collect anything worth keeping and
+  clear the directory by hand between courses.
+- The site moved here from `laser.baobab.band` on the home estate in August
+  2026; `laser.makerfloss.eu` is the canonical address.
