+└── README.md             # Diese Datei
+```
+
+## Umgebungsvariablen
+
+Die Anwendung verwendet folgende Umgebungsvariablen (definiert in `.env`):
+
+```env
+# Symfony
+APP_ENV=dev
+APP_SECRET=<generierter-secret-key>
+
+# Datenbank
+DATABASE_URL="mysql://immorechner_user:immorechner_pass@db:3306/immorechner?serverVersion=mariadb-11.7.1&charset=utf8mb4"
+
+# CORS
+CORS_ALLOW_ORIGIN='^https?://(localhost|127\.0\.0\.1)(:[0-9]+)?$'
+
+# Routing
+DEFAULT_URI=http://localhost
+```
+
+## Konfiguration
+
+### CORS anpassen
+
+CORS-Einstellungen können in `config/packages/nelmio_cors.yaml` angepasst werden.
+
+### Datenbank-Verbindung ändern
+
+Datenbank-Verbindung in `.env` anpassen:
+
+```env
+DATABASE_URL="mysql://user:password@host:port/database?serverVersion=mariadb-11.7.1"
+```
+
+### Apache-Konfiguration
+
+Apache-VirtualHost-Konfiguration befindet sich in `docker/apache/000-default.conf`.
+
+## Fehlerbehebung
+
+### Container starten nicht
+
+```bash
+# Container-Logs prüfen
+docker-compose logs
+
+# Container-Status prüfen
+docker ps -a
+
+# Container neu bauen
+docker-compose down
+docker-compose up -d --build
+```
+
+### "Class not found" Fehler
+
+```bash
+# Autoloader neu generieren
+docker-compose exec web composer dump-autoload
+
+# Cache leeren
+docker-compose exec web php bin/console cache:clear
+
+# Container neu starten
+docker-compose restart web
+```
+
+### Datenbank-Verbindungsfehler
+
+```bash
+# Prüfen ob DB-Container läuft
+docker ps | grep db
+
+# DB-Logs prüfen
+docker-compose logs db
+
+# In DB-Container einloggen und testen
+docker-compose exec db mysql -u root -proot
+```
+
+### Port bereits belegt
+
+Wenn Port 8080, 8081 oder 3306 bereits belegt ist, können die Ports in `docker-compose.yml` angepasst werden:
+
+```yaml
+services:
+  web:
+    ports:
+      - "8090:80"  # Statt 8080:80
+```
+
+## API-Dokumentation
+
+Die vollständige API-Dokumentation ist verfügbar unter:
+- **Swagger UI**: http://localhost:8080/api
+
+Die API unterstützt mehrere Formate:
+- JSON-LD (Standard)
+- JSON
+- HTML
+
+Beispiel für JSON-Format:
+
+```bash
+curl -H "Accept: application/json" http://localhost:8080/api/users
+```
+
+## Sicherheitshinweise
+
+**Wichtig für Produktion:**
+
+1. Ändern Sie alle Standardpasswörter in `docker-compose.yml` und `.env`
+2. Generieren Sie einen neuen `APP_SECRET` für `.env`
+3. Setzen Sie `APP_ENV=prod` in der Produktion
+4. Konfigurieren Sie CORS entsprechend Ihrer Domain
+5. Aktivieren Sie HTTPS
+6. Verwenden Sie sichere Datenbank-Credentials
+7. Entfernen Sie phpMyAdmin aus der Produktion
