+
+## 🚀 Quick Start
+
+### Prerequisites
+
+- Python 3.10 or higher
+- Docker (optional, for containerized deployment)
+- Azure subscription (for production deployment)
+
+### Local Development Setup
+
+1. **Clone the repository**
+```bash
+   git clone https://github.com/your-org/penny-v2.git
+   cd penny-v2
+```
+
+2. **Create virtual environment**
+```bash
+   python -m venv venv
+   source venv/bin/activate  # On Windows: venv\Scripts\activate
+```
+
+3. **Install dependencies**
+```bash
+   pip install --upgrade pip
+   pip install -r requirements.txt
+```
+
+4. **Configure environment variables**
+```bash
+   # Create .env file with required variables:
+   # AZURE_MAPS_KEY=your_azure_maps_key
+   # ENVIRONMENT=development
+   # DEBUG_MODE=false
+```
+
+5. **Run the application**
+```bash
+   uvicorn app.main:app --reload --host 0.0.0.0 --port 8000
+```
+
+6. **Access the API**
+   - API: http://localhost:8000
+   - Interactive docs: http://localhost:8000/docs
+   - Health check: http://localhost:8000/health
+
+---
+
+## 🐳 Docker Deployment
+
+### Build the container
+```bash
+docker build -t penny:latest .
+```
+
+### Run locally with Docker
+```bash
+docker run -p 8000:8000 \
+  -e AZURE_OPENAI_KEY=your_key \
+  -e WEATHER_API_KEY=your_key \
+  penny:latest
+```
+
+---
+
+## ☁️ Azure ML Deployment
+
+### 1. Create Azure Resources
+```bash
+# Create resource group
+az group create --name penny-rg --location eastus
+
+# Create Azure ML workspace
+az ml workspace create --name penny-workspace -g penny-rg
+
+# Create Azure Container Registry
+az acr create --name pennyregistry --resource-group penny-rg --sku Basic
+```
+
+### 2. Build and Push Container
+```bash
+# Login to Azure Container Registry
+az acr login --name pennyregistry
+
+# Build and tag image
+docker build -t pennyregistry.azurecr.io/penny:v1 .
+
+# Push to registry
+docker push pennyregistry.azurecr.io/penny:v1
+```
+
+### 3. Deploy to Azure Container Instances
+```bash
+az container create \
+  --resource-group penny-rg \
+  --name penny-api \
+  --image pennyregistry.azurecr.io/penny:v1 \
+  --cpu 2 \
+  --memory 4 \
+  --registry-login-server pennyregistry.azurecr.io \
+  --registry-username <username> \
+  --registry-password <password> \
+  --dns-name-label penny-civic-ai \
+  --ports 8000 \
+  --environment-variables \
+    ENVIRONMENT=production \
+    AZURE_OPENAI_KEY=<your-key>
+```
+
+---
+
+## 🔧 Configuration
+
+### Environment Variables
+
+| Variable | Description | Required | Default |
+|----------|-------------|----------|---------|
+| `ENVIRONMENT` | Deployment environment (`development`, `production`) | No | `development` |
+| `AZURE_MAPS_KEY` | Azure Maps API key (for weather) | Yes | - |
+| `ENVIRONMENT` | Deployment environment | No | `development` |
+| `DEBUG_MODE` | Enable debug endpoints | No | `false` |
+| `ALLOWED_ORIGINS` | CORS allowed origins (comma-separated) | No | `*` |
+| `LOG_LEVEL` | Logging level (`INFO`, `DEBUG`, `WARNING`) | No | `INFO` |
+| `TENANT_ID` | Default tenant/city identifier | No | `default` |
+
+### Azure Key Vault Integration (Recommended)
+
+For production deployments, store secrets in Azure Key Vault:
+```bash
+# Create Key Vault
+az keyvault create --name penny-keyvault --resource-group penny-rg
+
+# Store secrets
+az keyvault secret set --vault-name penny-keyvault --name openai-key --value "your-key"
+
+# Reference in deployment
+--environment-variables \
+  AZURE_OPENAI_KEY="@Microsoft.KeyVault(SecretUri=https://penny-keyvault.vault.azure.net/secrets/openai-key/)"
+```
+
+---
+
+## 📡 API Usage
+
+### Send a message to Penny
+```bash
+curl -X POST "http://localhost:8000/chat" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "message": "What community events are happening this weekend?",
+    "tenant_id": "norfolk",
+    "user_id": "user123",
+    "session_id": "session456"
+  }'
+```
+
+### Response format
+```json
+{
+  "response": "Hi! Here are some great community events happening this weekend in Norfolk...",
+  "intent": "community_events",
+  "tenant_id": "norfolk",
+  "session_id": "session456",
+  "timestamp": "2025-11-26T10:30:00Z",
+  "response_time_ms": 245
+}
+```
+
+---
+
+## 🧪 Testing
+
+### Run unit tests
+```bash
+pytest tests/ -v
+```
+
+### Run integration tests
+```bash
+pytest tests/integration/ -v
+```
+
+### Check code quality
+```bash
+# Linting
+flake8 app/ models/
+
+# Type checking
+mypy app/ models/
+
+# Format check
+black --check app/ models/
+```
+
+---
+
+## 📊 Monitoring & Logging
+
+Penny uses structured JSON logging for production observability:
+
+- **Application logs**: Stored in `/logs/` directory
+- **Azure Application Insights**: Integration available for production
+- **Health endpoint**: `/health` provides service status
+
+### Log format
+```json
+{
+  "timestamp": "2025-11-26T10:30:00Z",
+  "level": "INFO",
+  "intent": "weather_query",
+  "tenant_id": "norfolk",
+  "session_id": "abc123",
+  "response_time_ms": 150,
+  "success": true,
+  "model_used": "gpt-4"
+}
+```
+
+---
+
+## 🛡️ Security & Privacy
+
+- **PII Protection**: All logs sanitized before storage
+- **Content Moderation**: Built-in bias and safety detection
+- **Secrets Management**: Azure Key Vault integration
+- **Non-root Container**: Security-hardened Docker image
+- **HTTPS Only**: TLS/SSL required for production endpoints
+
+---
+
