 In this example:
 - The `MyService` class has a `proxy` attribute that connects to a `pydase` service at `<ip_addr>:<service_port>`.
 - By setting `block_until_connected=False`, the service can start without waiting for the connection to succeed.
-- By setting `client_id`, the server will log a descriptive identifier for this client via the `X-Client-Id` HTTP header.
+- The `client_id` is optional. If not specified, it defaults to the system hostname, which will be sent in the `X-Client-Id` HTTP header for logging or authentication on the server side.
