+
+## ⚙️ Konfiguration
+
+### config.js - Zentrale Konfiguration
+
+Alle Einstellungen sind in **einer** Datei:
+
+```javascript
+// config.js
+export const CONFIG = {
+  A: {
+    name: "Alice",              // Name Person A
+    colorHex: "#2ecc71",        // Farbe im Web (Grün)
+    colorDiscord: 0x2ecc71,     // Farbe in Discord (gleich!)
+    icon: "a.png",              // Profilbild
+    background: "bgA.jpg"       // Hintergrundbild
+  },
+  B: {
+    name: "Bob",                // Name Person B
+    colorHex: "#e74c3c",        // Farbe im Web (Rot)
+    colorDiscord: 0xe74c3c,     // Farbe in Discord (gleich!)
+    icon: "b.png",              // Profilbild
+    background: "bgB.jpg"       // Hintergrundbild
+  }
+};
+
+// Discord Webhook (optional)
+export const DISCORD_WEBHOOK_URL = "https://discord.com/api/webhooks/...";
+
+// Öffentliche URL (für Discord Thumbnails)
+export const PUBLIC_BASE_URL = "https://your-domain.com";
+```
+
+### Farben ändern
+
+```javascript
+// Blau & Orange
+A: { colorHex: "#3498db", colorDiscord: 0x3498db }
+B: { colorHex: "#e67e22", colorDiscord: 0xe67e22 }
+
+// Lila & Pink
+A: { colorHex: "#9b59b6", colorDiscord: 0x9b59b6 }
+B: { colorHex: "#e91e63", colorDiscord: 0xe91e63 }
+
+// Türkis & Gold
+A: { colorHex: "#1abc9c", colorDiscord: 0x1abc9c }
+B: { colorHex: "#f39c12", colorDiscord: 0xf39c12 }
+```
+
+**Wichtig:** Hex-Farbe muss genau 6 Zeichen haben (0-9, A-F)!

+4. Tippe **"Hinzufügen"**
+
+### Android (Chrome)
+
+1. Öffne die Website in Chrome
+2. Tippe auf **Menü** (⋮)
+3. Tippe **"App installieren"**
+4. Tippe **"Installieren"**
+
+### Desktop (Chrome/Edge)
+

+2. Klicke auf das **⊕ Icon** in der Adressleiste
+3. Oder: Menü → "WhoPays installieren"
+
+**Wichtig:** PWA funktioniert nur über HTTPS (oder localhost)!
+
+---
+
+## 🔒 Reverse Proxy Setup
+
+### Nginx
+
+```nginx
+server {
+    listen 443 ssl http2;
+    server_name whopays.your-domain.com;
+    
+    # PWA Files - NO AUTH
+    location ~ ^/(service-worker\.js|manifest\.json)$ {
+        proxy_pass http://localhost:3000;
+        proxy_set_header X-Forwarded-Proto $scheme;
+        add_header Service-Worker-Allowed "/" always;
+    }
+    
+    # Main app
+    location / {
+        proxy_pass http://localhost:3000;
+        proxy_set_header Host $host;
+        proxy_set_header X-Forwarded-Proto $scheme;
+    }
+}
+```
+
+### Caddy (Einfachste Option!)
+
+```caddy
+whopays.your-domain.com {
+    reverse_proxy localhost:3000
+}
+```
+
+Caddy macht automatisch HTTPS mit Let's Encrypt! ✅
+
+---
+
+## 🔧 API Endpoints
+
+### GET /status
+
+```bash
+curl http://localhost:3000/status
+```
+
+Response:
+```json
+{
+  "current": "A",
+  "lastReason": "Pizza bestellt"
+}
+```
+
+### POST /toggle
+
+```bash
+curl -X POST http://localhost:3000/toggle \
+  -H "Content-Type: application/json" \
+  -d '{"reason":"Kaffee trinken"}'
+```
+
+Response:
+```json
+{
+  "current": "B",
+  "name": "Bob",
+  "lastReason": "Kaffee trinken"
+}
+```
+
+### GET /config
+
+```bash
+curl http://localhost:3000/config
+```
+
+---
+
+## 🐛 Troubleshooting
+
+### PWA lässt sich nicht installieren
+
+- Stelle sicher, dass du HTTPS verwendest
+- Prüfe ob `manifest.json` erreichbar ist
+- Icons müssen existieren: `icon-192.png` und `icon-512.png`
+
+### Discord sendet keine Benachrichtigungen
+
+- Prüfe Webhook URL in `config.js`
+- Logs prüfen: `docker-compose logs | grep Discord`
+- Stelle sicher `PUBLIC_BASE_URL` ist korrekt
+
+### Bilder werden nicht angezeigt
+
+- Prüfe ob Bilder in `/img/` existieren
+- Berechtigungen: `chmod -R 755 img/`
+- Container neu starten
+
+### Farbe in Discord ungültig (HTTP 400)
+
+- Hex-Farbe muss genau 6 Zeichen haben
+- ✅ Richtig: `0x2ecc71`
+- ❌ Falsch: `0x2ecc71c` (extra Buchstabe!)
+
+---
+
+## 📊 Features im Detail
+
+### Persistent Storage
+
+```json
+{
+  "current": "A",
+  "lastReason": "Restaurant bezahlt"
+}
+```
+
+Bleibt erhalten durch Docker Volume Mount.
+
+### Smooth Animations
+
+- Rotation-Animation (0.6s)
+- Background-Transition (0.6s)
+- Farb-Übergang (0.3s)
+- Image Preloading
+
+---
+
+## 📜 Lizenz
+
+MIT License - Frei nutzbar!
+
+---
+
+## 💡 Tipps
+
+### Custom Domain mit Let's Encrypt
+
+```bash
+sudo certbot --nginx -d whopays.your-domain.com
+```
+
+### Mehrere Instanzen
+
+Unterschiedliche Ports in docker-compose.yml für mehrere Apps!
