-The following example limits the request rate to the `billing` service when requests begin with `/api` and `/login`.
+The following example configures the default behavior for a service named `billing`. This configuration limits each instance of the billing service depending on the path it received the request on. The service is limited to an average of 500 requests when the request is made on an HTTP path with the `/api` prefix. When an instance of the billing service receives a request from the `/login` path, it is limited to an average of 100 requests per second and 500 concurrent connections.
