+# MathQuest - Mathe-Lernseite für Kinder
+
+Eine einfache und spaßige Mathe-Lernseite mit Quest-Punktesystem für Kinder.
+
+## Features
+
+- 🎯 Einfache Mathe-Aufgaben (Addition, Subtraktion, Multiplikation)
+- ⭐ Quest-Punktesystem - jede Aufgabe gibt Punkte
+- 📊 Fortschrittsbalken zur Visualisierung der Gesamtpunktzahl
+- 💾 Persistente Speicherung der Punkte (JSON-Datei)
+- 🎨 Kindgerechtes, buntes Design
+
+## Installation
+
+1. Node.js installieren (falls noch nicht vorhanden)
+
+2. Abhängigkeiten installieren:
+```bash
+npm install
+```
+
+## Starten
+
+```bash
+npm start
+```
+
+Die Seite läuft dann auf `http://localhost:3000`
+
+## Auf VPS deployen
+
+1. Code auf den VPS hochladen
+2. `npm install` ausführen
+3. Mit PM2 oder systemd als Service laufen lassen:
+
+### Mit PM2:
+```bash
+npm install -g pm2
+pm2 start server.js --name mathquest
+pm2 save
+pm2 startup
+```
+
+### Mit systemd:
+Erstelle eine Service-Datei `/etc/systemd/system/mathquest.service`:
+```ini
+[Unit]
+Description=MathQuest Server
+After=network.target
+
+[Service]
+Type=simple
+User=dein-user
+WorkingDirectory=/pfad/zum/mathquest
+ExecStart=/usr/bin/node server.js
+Restart=always
+
+[Install]
+WantedBy=multi-user.target
+```
+
+Dann:
+```bash
+sudo systemctl enable mathquest
+sudo systemctl start mathquest
+```
+
+4. Nginx als Reverse Proxy konfigurieren (optional)
+
+## Architektur
+
+- **tasks.json**: Enthält alle Mathe-Aufgaben (Fragen, Antworten, Punkte)
+ - Wird beim Prüfen von Antworten aktualisiert
+ - Speichert `userAnswer` und `isCorrect` für jede Aufgabe
+- **Backend**: Prüft Antworten und speichert sie direkt in der Task
+- **Frontend**: Lädt Aufgaben, berechnet Gesamtpunktzahl aus korrekt beantworteten Aufgaben
+
+## API Endpoints
+
+- `GET /api/tasks` - Lädt alle Aufgaben (inkl. gespeicherte Antworten)
+- `POST /api/check-answer` - Prüft eine Antwort (taskId, answer)
+ - Speichert `userAnswer` und `isCorrect` in der Task
+ - Gibt zurück: `correct`, `correctAnswer`, `points`
+
+## Anpassungen
+
+- Aufgaben können in `tasks.json` angepasst werden
+- Design kann in `public/style.css` angepasst werden
+- Port kann über Umgebungsvariable `PORT` geändert werden
