-## Verification
+## 🚀 Server Management
 
-CLI tested with:
-- No arguments: `go run ./cmd/greet` → "Hello world!"
-- With argument: `go run ./cmd/greet John` → "Hello John!"
+### Starting the Server
+
+```bash
+# Navigate to project directory
+cd /Users/gabrielradureau/Work/Vibe/DanceLessonsCoach
+
+# Run server in background
+go run cmd/server/main.go &
+```
+
+**Expected output:**
+```
+Server running on :8080
+[INF] Starting HTTP server on :8080
+[TRC] Registering greet routes
+[TRC] Greet routes registered
+```
+
+**Features:**
+- Context-aware server initialization
+- Graceful shutdown handling
+- Signal-based termination (SIGINT, SIGTERM)
+- 30-second shutdown timeout
+- Proper resource cleanup
+
+### Checking Server Status
+
+```bash
+# Check health endpoint
+curl -s http://localhost:8080/api/health
+```
+
+**Expected response:** `{"status":"healthy"}`
+
+### Stopping the Server
+
+To stop the server gracefully:
+```bash
+# Send SIGTERM for graceful shutdown
+pkill -TERM -f "go run"
+
+# Or send SIGINT (Ctrl+C equivalent)
+pkill -INT -f "go run"
+```
+
+**Graceful shutdown process:**
+1. Server receives termination signal
+2. Logs shutdown message
+3. Stops accepting new connections
+4. Waits up to 30 seconds for active requests to complete
+5. Closes all connections cleanly
+6. Exits with proper cleanup
+
+For force stop (if graceful shutdown hangs):
+```bash
+pkill -f "go"
+```
+
+**Verification:**
+```bash
+curl -s http://localhost:8080/api/health
+# Should return connection refused
+```
+
+## 🌐 API Endpoints
+
+### Base URL
+```
+http://localhost:8080
+```
+
+### Health Check
+```http
+GET /api/health
+```
+
+**Response:**
+```json
+{"status":"healthy"}
+```
+
+### Greet Service
+```http
+GET /api/v1/greet/
+GET /api/v1/greet/{name}
+```
+
+**Examples:**
+```bash
+# Default greeting
+curl http://localhost:8080/api/v1/greet/
+# Response: {"message":"Hello world!"}
+
+# Personalized greeting
+curl http://localhost:8080/api/v1/greet/John
+# Response: {"message":"Hello John!"}
+
+# Another example
+curl http://localhost:8080/api/v1/greet/Alice
+# Response: {"message":"Hello Alice!"}
+```
+
+## 🔧 Development Workflow
+
+### 1. Check Server Status
+```bash
+curl -s http://localhost:8080/api/health
+```
+
+### 2. Start Development Server
+```bash
+cd /Users/gabrielradureau/Work/Vibe/DanceLessonsCoach
+go run cmd/server/main.go &
+```
+
+### 3. Test API Endpoints
+```bash
+# Test all endpoints as shown above
+curl http://localhost:8080/api/v1/greet/YourName
+```
+
+### 4. Run Tests
+```bash
+# Run all tests
+go test ./...
+
+# Run specific package
+go test ./pkg/greet/
+```
+
+### 5. Make Changes
+- Edit source files in `pkg/` or `cmd/`
+- Follow existing patterns and interfaces
+- Add tests for new functionality
+
+### 6. Stop and Restart
+```bash
+pkill -f "go"
+go run cmd/server/main.go &
+```
+
+## 🧪 Testing
+
+### Unit Tests
+```bash
+# Run all tests
+go test ./...
+
+# Run with verbose output
+go test -v ./...
+
+# Run specific test
+go test ./pkg/greet/ -run TestService_Greet
+```
+
+### CLI Testing
+```bash
+# Default greeting
+go run ./cmd/greet
+# Output: Hello world!
+
+# Personalized greeting
+go run ./cmd/greet John
+# Output: Hello John!
+```
+
+### API Testing
+```bash
+# Health check
+curl http://localhost:8080/api/health
+
+# Greet endpoints
+curl http://localhost:8080/api/v1/greet/John
+curl http://localhost:8080/api/v1/greet/
+```
+
+## 📝 Architecture Decisions
+
+### Interface-Based Design
+```go
+type Greeter interface {
+    Greet(ctx context.Context, name string) string
+}
+```
+
+**Benefits:**
+- Easy mocking for tests
+- Dependency injection
+- Multiple implementations
+- Clear contracts
+
+### Context-Aware Services
+```go
+func (s *Service) Greet(ctx context.Context, name string) string {
+    log.Trace().Ctx(ctx).Str("name", name).Msg("Greet function called")
+    // ...
+}
+```
+
+**Benefits:**
+- Request tracing
+- Cancellation support
+- Deadline propagation
+- Metadata passing
+
+### Server Context Management
+```go
+// Root context with cancellation
+ctx, cancel := context.WithCancel(context.Background())
+defer cancel()
+
+// Server context with graceful shutdown
+serverCtx, serverStop := context.WithCancel(ctx)
+
+// HTTP server with context-aware shutdown
+srv := &http.Server{
+	Addr:    ":8080",
+	Handler: server.Router(),
+}
+
+// Graceful shutdown with timeout
+shutdownCtx, shutdownCancel := context.WithTimeout(
+	context.Background(), 
+	30*time.Second
+)
+defer shutdownCancel()
+
+if err := srv.Shutdown(shutdownCtx); err != nil {
+	log.Error().Err(err).Msg("Server shutdown failed")
+}
+```
+
+**Benefits:**
+- Graceful shutdown handling
+- Signal-based termination (SIGINT, SIGTERM)
+- 30-second timeout for active connections
+- Proper resource cleanup
+- Context propagation throughout server lifecycle
+
+### Zerolog Logging
+```go
+zerolog.SetGlobalLevel(zerolog.TraceLevel)
+log.Logger = log.Output(zerolog.ConsoleWriter{Out: os.Stderr})
+```
+
+**Benefits:**
+- High performance
+- Structured logging
+- Trace level detail
+- Color output
+
+### Versioned API
+```go
+router.Route("/api/v1", func(r chi.Router) {
+    // v1 endpoints
+})
+```
+
+**Benefits:**
+- Backward compatibility
+- Clear versioning
+- Easy migration
+- Parallel versions
+
+## 🔍 Troubleshooting
+
+### Port Already in Use
+```bash
+# Find process using port 8080
+lsof -i :8080
+
+# Kill the process
+kill -9 <PID>
+```
+
+### Server Not Responding
+```bash
+# Check if running
+curl -s http://localhost:8080/api/health
+
+# Restart server
+pkill -f "go"
+go run cmd/server/main.go &
+```
+
+### Dependency Issues
+```bash
+# Clean and rebuild
+go mod tidy
+go build ./...
+```
+
+### Tests Failing
+```bash
+# Run with verbose output
+go test -v ./...
+
+# Check specific test
+go test ./pkg/greet/ -run TestName
+```
+
+## 📚 Code Examples
+
+### Adding New API Endpoint
+```go
+// 1. Add to interface
+func (h *apiV1GreetHandler) RegisterRoutes(router chi.Router) {
+    router.Get("/", h.handleGreetQuery)
+    router.Get("/{name}", h.handleGreetPath)
+    router.Post("/custom", h.handleCustomGreet) // New endpoint
+}
+
+// 2. Implement handler
+func (h *apiV1GreetHandler) handleCustomGreet(w http.ResponseWriter, r *http.Request) {
+    // Parse request
+    // Call service
+    // Return JSON response
+}
+```
+
+### Adding Logging
+```go
+// Trace level logging
+log.Trace().Ctx(ctx).Str("key", "value").Msg("message")
+
+// Info level
+log.Info().Msg("Important event")
+
+// Error level
+log.Error().Err(err).Msg("Error occurred")
+```
+
+### Using Context
+```go
+// Pass context through calls
+func handler(w http.ResponseWriter, r *http.Request) {
+    result := service.Greet(r.Context(), "John")
+    // ...
+}
+
+// Create context with values
+ctx := context.WithValue(r.Context(), "key", "value")
+
+// Create context with timeout
+ctx, cancel := context.WithTimeout(r.Context(), 5*time.Second)
+defer cancel()
+```
+
+## 🎓 Best Practices
+
+### Code Organization
+- Keep handlers thin, move logic to services
+- Use interfaces for dependencies
+- Separate route registration from handlers
+- Group related functionality
+
+### Error Handling
+- Return proper HTTP status codes
+- Log errors with context
+- Don't expose internal errors to clients
+- Use structured error responses
+
+### Performance
+- Use Zerolog's Trace level sparingly in production
+- Avoid allocations in hot paths
+- Use context timeouts for external calls
+- Batch database operations
+
+### Testing
+- Test interfaces, not implementations
+- Use table-driven tests
+- Test error cases
+- Mock dependencies
+
