+
+## 🚀 Quick Start
+
+### Using Docker (Recommended)
+
+```bash
+# Pull and run the latest image
+docker run -d \
+  --name baby-monitor \
+  -p 8000:8000 \
+  -e ADMIN_PASSWORD=your-secure-password \
+  -v baby_monitor_data:/data \
+  gitea.gt-proj.com/brian/baby-monitor:latest
+
+# Access the application
+open http://localhost:8000
+```
+
+### Using Docker Compose
+
+```yaml
+services:
+  baby-monitor:
+    image: gitea.gt-proj.com/brian/baby-monitor:latest
+    container_name: baby-monitor
+    ports:
+      - "8000:8000"
+    environment:
+      - ENVIRONMENT=production
+      - ADMIN_PASSWORD=${ADMIN_PASSWORD}
+      # Optional: Use Redis for distributed token storage
+      # - REDIS_URI=redis://redis:6379
+    volumes:
+      - ./data:/data
+    restart: unless-stopped
+
+  # Optional: Redis for token storage
+  # redis:
+  #   image: redis:7-alpine
+  #   restart: unless-stopped
+```
+
+### Local Development
+
+```bash
+# Clone the repository
+git clone https://gitea.gt-proj.com/brian/baby-monitor.git
+cd baby-monitor
+
+# Install dependencies with uv
+uv sync --all-extras
+
+# Set environment variables
+export ENVIRONMENT=development
+export ADMIN_PASSWORD=password
+export DATA_DIR=./data
+
+# Run the application
+uv run uvicorn src.baby_monitor.main:app --reload --host 0.0.0.0 --port 8000
+```
+
+## 🔧 Configuration
+
+### Environment Variables
+
+| Variable         | Default      | Description                                 |
+| ---------------- | ------------ | ------------------------------------------- |
+| `ENVIRONMENT`    | `production` | Set to `development` to enable API docs     |
+| `ADMIN_PASSWORD` | _(required)_ | Admin user password                         |
+| `ADMIN_USERNAME` | `admin`      | Admin username                              |
+| `DATA_DIR`       | `/data`      | Directory for SQLite database               |
+| `REDIS_URI`      | _(optional)_ | Redis connection URI for distributed tokens |
+
+### Storage Options
+
+**SQLite (Default)**
+
+- Automatic setup, no configuration needed
+- Data stored in `/data/baby_monitor.db`
+- Perfect for single-server deployments
+
+**Redis (Optional)**
+
+```bash
+# Enable Redis token storage
+export REDIS_URI=redis://localhost:6379
+```
+
+**PostgreSQL (Future)**
+
+- Repository interface ready
+- Swap implementation in `dependencies.py`

+
+## 🏗️ Architecture
+
+### Repository Pattern
+
+The application uses the **Repository Pattern** for data access, allowing easy swapping of backends:
+
+```python
+# Switch from SQLite to PostgreSQL
+from baby_monitor.repositories.user.postgresql_user import PostgreSQLUserRepository
+return PostgreSQLUserRepository(db)
+
+# Switch from in-memory to Redis tokens
+# Just set REDIS_URI environment variable
+```
+
+### Technology Stack
+
+- **Backend**: FastAPI + SQLAlchemy 2.0
+- **Database**: SQLite (default) / PostgreSQL (ready)
+- **Cache**: In-memory (default) / Redis (optional)
+- **Package Manager**: uv
+- **Container**: Docker with multi-stage builds
+
+## 🧪 Testing
+
+```bash
+# Run all tests
+uv run pytest
+
+# Run with coverage
+uv run pytest --cov-report=term-missing --cov=src/baby_monitor
+
+# Run specific test types
+uv run pytest tests/unit/
+uv run pytest tests/integration/
+```
+
+## 🔒 Security
+
+- ✅ Token-based authentication
+- ✅ Environment-based secrets (no hardcoded credentials)
+- ✅ API docs disabled in production
+- ✅ CORS configuration ready
+- ⚠️ **TODO**: Add password hashing (currently plain text comparison)
+- ⚠️ **TODO**: Implement rate limiting
+
+## 🚀 Deployment
+
+### Unraid
+
+1. Add the repository to Community Applications
+2. Configure environment variables
+3. Map `/data` volume for persistence
+4. Set admin password
+
+### Docker Swarm / Kubernetes
+
+The application is stateless when using Redis for tokens, making it suitable for:
+
+- Multi-replica deployments
+- Load balancing
+- Rolling updates
+
+### CI/CD
+
+Gitea Actions workflow included:
+
+- Builds multi-architecture images (amd64, arm64)
+- Automatic semantic versioning
+- Pushes to container registry
+- Health checks and metadata
+
+## 📊 API Documentation
+
+When running in development mode (`ENVIRONMENT=development`):
+
+- **OpenAPI Docs**: http://localhost:8000/docs
+- **ReDoc**: http://localhost:8000/redoc
+- **OpenAPI JSON**: http://localhost:8000/openapi.json
+
+### Key Endpoints
