	// wire all routes to their handlers
	// we can directly do
	// router.GET("/retrieve", handler.Retrieve)
	// but it gets messy fast : and at scale (50 routes), it becomes difficult to maintain
	// so we use routes.go to wire all routes to their handlers
	// routes.go is a better way to organize routes

	// Run internally uses ListenAndServe() to start the server on the port specified in the router.
