 # Hitstar – lokale Web-App (Prototyp)
 
+## Docker
+
+Run the app in a container while using your local `data/` music folder:
+
+1) Build the image
+
+```powershell
+docker compose build
+```
+
+2) Start the service
+
+```powershell
+docker compose up -d
+```
+
+3) Open http://localhost:5173
+
+Notes:
+- Your local `data/` is mounted read/write at `/app/data` inside the container, so you can manage tracks on the host.
+- To rebuild after changes: `docker compose build --no-cache && docker compose up -d`.
+
 Lokales Multiplayer-Webspiel inspiriert von HITSTER. Nutzt eure MP3-Dateien im Ordner `data/`, eine Lobby mit Raum-Code sowie WebSockets für den Mehrspieler-Modus.
