-                Here we create the `Router`. We add a logging middleware to it (this logs all requests to the router). The function uses a result builder to create a stack of middleware, but you can also use `Router.add(middleware:)` to add individual middleware. Finally we add a single endpoint GET `/health` which returns a 200 (Ok) response.
