 ## Hinweise fuer Debian 13 und NGINX
 
-- NGINX kann nativ auf dem Host laufen und auf `127.0.0.1:8000` proxyen.
+- NGINX kann nativ auf dem Host laufen und auf `127.0.0.1:8001` proxyen.
 - Das Backend lauscht absichtlich nur auf `127.0.0.1`, damit es nicht direkt aus dem Internet erreichbar ist.
 - Fuer produktiven Betrieb solltest du TLS im NGINX-Terminator aktivieren.
+- Setze `EVENTLENS_AUTH_USERNAME` und `EVENTLENS_AUTH_PASSWORD`, wenn Eventlens ueber NGINX, VPN oder Tunnel erreichbar ist.
 - Das Frontend wird direkt vom FastAPI-Container ausgeliefert, es ist kein Node- oder Build-Container noetig.
