+# Habit Tracker
+
+Ein einfacher Habit Tracker mit wöchentlicher Ansicht, gebaut mit Flask und JavaScript.
+
+## Features
+
+- 📅 Wöchentliche Ansicht (7 Zeilen für jeden Wochentag)
+- 🎯 Anpassbare Tagesziele (1-20x pro Tag)
+- 🎨 Individuelle Farben für jedes Habit
+- 🔥 Streak-Zähler
+- 📱 Responsive Design
+- 🐳 Docker-Support
+
+## Schnellstart mit Docker
+
+### Aus der Registry
+```bash
+docker run -d \
+  --name habit-tracker \
+  -p 5000:5000 \
+  -v habit-data:/app/data \
+  gitea.example.com/username/habit-tracker:latest
+```
+
+### Lokal bauen
+```bash
+# Repository klonen
+git clone <repository-url>
+cd habit-tracker
+
+# Mit Docker Compose
+docker-compose up -d
+
+# Oder manuell
+docker build -t habit-tracker .
+docker run -d \
+  --name habit-tracker \
+  -p 5000:5000 \
+  -v habit-data:/app/data \
+  habit-tracker
+```
+
+## Lokale Entwicklung
+
+```bash
+# Virtual Environment erstellen
+python -m venv venv
+source venv/bin/activate  # Linux/Mac
+# oder
+venv\Scripts\activate     # Windows
+
+# Dependencies installieren
+pip install -r requirements.txt
+
+# App starten
+python app.py
+```
+
+Die App ist dann unter http://localhost:5000 erreichbar.
+
+## Konfiguration
+
+### Umgebungsvariablen
+- `FLASK_ENV`: `production` oder `development` (Standard: `production`)
+- `FLASK_APP`: `app.py` (Standard)
+
+### Volumes
+- `/app/data`: Hier wird die `habits.json` Datenbank gespeichert
+
+## Deployment
+
+### Docker Compose (Empfohlen)
+```yaml
+version: '3.8'
+
+services:
+  habit-tracker:
+    image: gitea.example.com/username/habit-tracker:latest
+    ports:
+      - "5000:5000"
+    volumes:
+      - ./data:/app/data
+    environment:
+      - FLASK_ENV=production
+    restart: unless-stopped
+```
+
+### Reverse Proxy (Nginx)
+```nginx
+server {
+    listen 80;
+    server_name habits.example.com;
+
+    location / {
+        proxy_pass http://localhost:5000;
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+        proxy_set_header X-Forwarded-Proto $scheme;
+    }
+}
+```
+
+## Bedienung
+
+1. **Habit hinzufügen**: Namen eingeben und "Hinzufügen" klicken
+2. **Heute abhaken**: ✓-Button klicken (zeigt Fortschritt bei Zielen >1)
+3. **Vergangene Tage bearbeiten**: Drei-Punkte-Menü → Modal öffnen
+4. **Einstellungen**: Im Modal Farbe und Tagesziel anpassen
+5. **Löschen**: Im Modal über den "Löschen"-Button
+
+## Technische Details
+
+- **Backend**: Flask (Python)
+- **Frontend**: Vanilla JavaScript
+- **Datenbank**: TinyDB (JSON-basiert)
+- **Styling**: CSS Grid/Flexbox
+- **Container**: Multi-Arch (AMD64/ARM64)
+
+## CI/CD
+
+Der Gitea-Workflow baut automatisch Docker-Images bei:
+- Push auf `main`/`master` Branch
+- Neue Tags (z.B. `v1.0.0`)
+- Pull Requests
