 3. In NPM, add a proxy host for `NEXTCLOUD_DOMAIN` → `http://nextcloud:80` with SSL enabled
 4. Open https://NEXTCLOUD_DOMAIN and create the admin account (the database fields are pre-filled from the environment)
 
+To test without NPM, open http://HOST_IP:8084. Set `NEXTCLOUD_DOMAIN=HOST_IP` and `NEXTCLOUD_OVERWRITEPROTOCOL=http` first. Otherwise Nextcloud rejects the untrusted domain and redirects you to https links that don't work.
