+## Bekannte Betriebsfalle
+
+Wenn MariaDB bereits mit aelteren Zugangsdaten initialisiert wurde, reicht eine Aenderung in `.env` allein nicht aus. In dem Fall bleibt das Docker-Volume bestehen und der App-User in MariaDB hat noch das alte Passwort.
+
+Zum Angleichen auf die aktuellen Werte aus `.env`:
+
+```bash
+cd /opt/eventlens
+sudo bash scripts/fix-db-user.sh
+```
+
+Wenn dir die Datenbank egal ist und du komplett frisch starten willst:
+
+```bash
+cd /opt/eventlens
+sudo docker compose down -v
+sudo docker compose up -d --build
+```
+
 ## Naechste sinnvolle Ausbaustufen
 
 - Web-Frontend fuer Watchlist und Events
 - Weitere Datenquellen neben Ticketmaster
 - Telegram oder Push-Benachrichtigungen
 - Nutzerverwaltung
+
+## Provider-Hinweise
+
+- Ticketmaster nutzt die offizielle Discovery API.
+- Bandsintown nutzt die offizielle Artist-Events-API und arbeitet deshalb vor allem fuer Watchlist-Eintraege vom Typ `artist`.
+- Eventim nutzt eine beobachtete oeffentliche JSON-Web-API von eventim.de. Das ist keine offiziell dokumentierte Developer-API, aber stabiler als HTML-Scraping. Aenderungen an diesem Web-Endpoint koennen trotzdem Anpassungen noetig machen.
