+
+	// Register some routes
+	fuego.Post(s, "/hello", myController)
+	fuego.Get(s, "/myPath", otherController)
+	fuego.Put(s, "/hello", thirdController)
+
+	adminRoutes := fuego.Group(s, "/admin")
+	fuego.Use(adminRoutes, myMiddleware) // This middleware (for authentication, etc...) will be available for routes starting by /admin/*, 
+	fuego.Get(adminRoutes, "/hello", groupController) // This route will be available at /admin/hello
+
+	// Start the server
