 #### Consumer
 
 1. Set up the `dubbo service` you need to subscribe to at the beginning of the program startup.
-   Make sure that the configuration file [client.yml](go-client/conf/client.yml) has been configured with the relevant information of the subscription service, and the service properties can be customized to override the configuration of the Provider's properties.
+   Make sure that the configuration file [dubbogo.yml](go-client/conf/dubbogo.yml) has been configured with the relevant information of the subscription service, and the service properties can be customized to override the configuration of the Provider's properties.
    Retain minimum configuration `application` and `references` verification point-to-point direct connection effect, no need to configure the registry.
