 1. If the Docker API enables TLS authentication, the edge node deployed as the server needs to configure the CA certificate, server certificate and server private key of the Docker API. ECP as the client needs to configure the CA certificate, client certificate and client private key of the Docker API. For specific configuration methods, please refer to [Docker TLS authentication](https://docs.docker.com/engine/security/https/).

   :::tip Note
   If ElasticSearch connection information is incorrectly configured, the logging function is unavailable, but other functions are not affected.

 - Execute the following command to start the ECP service.
-  `shell
-./emqx_ecp_ctl start
-`
+
+  ```shell
+  ./emqx_ecp_ctl start

   :::tip Note
   When starting the ECP service for the first time, you need to pull the software image from the public image repository, which may take some time. You can also [contact us](https://www.emqx.com/en/contact?product=emqx-ecp) to get the offline installation package.
