 ## Initialisierung des Projekts
 
@@ -40,23 +41,69 @@ Um das Projekt erfolgreich zu starten, folge diesen Schritten:
    ```
 7. Die Datenbank migrieren:
    ```sh
-   python3 core/manage.py migrate
+   python django/manage.py migrate
    ```
 
 ## Starten des Servers
 
 ### Entwicklungsserver starten
 
-Um den Server zu starten, verwende einen der folgenden Befehle:
+Für die Entwicklung mit WebSocket-Unterstützung verwenden wir Daphne:
 
-- Standardport (8000):
-  ```sh
-  python3 core/manage.py runserver
-  ```
-- Bestimmten Port (z. B. 9000):
-  ```sh
-  python3 core/manage.py runserver 9000
-  ```
+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
+   ```
+
+3. Starte den REDIS Server
+   ```sh
+   redis-server
+   ```
+   > **Hinweis:** Der Redis Server muss, wenn er nicht auf dem selben Gerät unter Standardeinstellungen läuft, in der Datei play/consumers/lobby.py und core/settings.py entsprechend umkonfiguriert werden!
+
+
+Alternativ kannst du den Django-Entwicklungsserver verwenden, wenn du keine WebSocket-Funktionalität benötigst:
+   ```sh
+   python3 core/manage.py runserver
+   ```
+
+### 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 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)
+
+4. Cronjob für Bereinigung der Spiele in der Datenbank
+   - Zum bearbeiten der Cronjobs:
+      ```sh
+      crontab -e
+      ```
+   - Dann `0 0 * * * /path/to/venv/bin/python /path/to/your_project/manage.py cleanup_games` einfügen, damit um Mitternacht alle Spiele gelöscht werden
+
+5. Starte den REDIS Server
+   ```sh
+   redis-server
+   ```
+   > **Hinweis:** Der Redis Server muss, wenn er nicht auf dem selben Gerät unter Standardeinstellungen läuft, in der Datei play/consumers/lobby.py und core/settings.py entsprechend umkonfiguriert werden!
 
 Damit ist das Projekt erfolgreich eingerichtet und der Server kann gestartet werden!
