 ### Entwicklungsserver starten
 
-Um den Server zu starten, verwende einen der folgenden Befehle:
+Für die Entwicklung mit WebSocket-Unterstützung verwenden wir Daphne:
 
-- Standardport (8000):
+1. Aktiviere die virtuelle Umgebung:
+   ```sh
+   source .venv/bin/activate  # Linux
+   .venv\Scripts\activate     # Windows
+   ```
+
+2. Starte den Daphne-Server:
+   ```sh
+   # Im Verzeichnis 'django'
+   daphne -b 127.0.0.1 -p 8000 core.asgi:application
+   ```
+
+Alternativ kannst du den Django-Entwicklungsserver verwenden, wenn du keine WebSocket-Funktionalität benötigst:
    ```sh
    python3 core/manage.py runserver
    ```
-- Bestimmten Port (z. B. 9000):
+
+### Produktionsserver starten
+
+Für den Produktivbetrieb verwenden wir Daphne als ASGI-Server, der sowohl HTTP als auch WebSocket-Verbindungen unterstützt:
+
+1. Aktiviere die virtuelle Umgebung wie oben beschrieben
+
+2. Sammle die statischen Dateien:
    ```sh
-  python3 core/manage.py runserver 9000
+   python3 core/manage.py collectstatic
    ```
 
+3. Starte den Daphne-Server:
+   ```sh
+   daphne -b 0.0.0.0 -p 8000 core.asgi:application
+   ```
+   - `-b 0.0.0.0`: Bindet den Server an alle Netzwerk-Interfaces
+   - `-p 8000`: Port (anpassbar)
+
 Damit ist das Projekt erfolgreich eingerichtet und der Server kann gestartet werden!
