## 🚀 Quick Start

1. **Initialize the project:**
   ```bash
   cd examples/comprehensive-rust-showcase
   ggen lifecycle init
   ```

2. **Run the complete lifecycle:**
   ```bash
   ggen lifecycle run
   ```

3. **Generate specific components:**
   ```bash
   ggen template generate templates/rust-service.tmpl
   ggen ai generate "Create a user authentication service"
   ggen graph query "SELECT ?service WHERE { ?service a ex:Microservice }"
   ```

4. **Deploy to different environments:**
   ```bash
   ggen lifecycle deploy --env development
   ggen lifecycle deploy --env staging
   ggen lifecycle deploy --env production
   ```

## 🔧 Advanced Features

### AI Integration Examples
```bash
# Generate code from natural language
ggen ai generate "Create a product catalog service with CRUD operations"

# Analyze existing code
ggen ai analyze generated/src/services/product.rs

# Optimize performance
ggen ai optimize generated/src/api/handlers.rs
```

### SPARQL Query Examples
```bash
# Find all entities
ggen graph query "SELECT ?entity WHERE { ?entity a ex:Entity }"

# Complex relationship queries
ggen graph query "SELECT ?user ?order WHERE { ?user ex:hasOrder ?order }"

# Generate code from query results
ggen template generate templates/rust-service.tmpl --sparql "find_services"
```

### Lifecycle Management
```bash
# Run specific phases
ggen lifecycle run --phases init,setup,generate

# Parallel execution
ggen lifecycle run --parallel

# Environment-specific deployment
ggen lifecycle deploy --env production --confirm
```
