 ### RustDesk Pro - Install Additional Relay Servers with Geo Location using docker
 
+{{% notice note %}}
+[The simple install](/docs/en/self-host/rustdesk-server-pro/installscript/) creates a relay server (the `hbbr` process) implicitly on the same machine, you do not need to specify relay server explicitly.
+
+If you wanna create additional relay server explicitly on another machine, please run `hbbr` by following [OSS installation](/docs/en/self-host/rustdesk-server-oss/install/). You can find `hbbr` in `rustdesk-server-linux-amd64.tar.gz`, `rustdesk-server-hbbr_<version>-<arch>.deb`, `rustdesk-server-windows-x86_64.tar.gz` or in `docker` (`sudo docker run --name hbbr -v ./data:/root -td --net=host --restart unless-stopped rustdesk/rustdesk-server-pro hbbr
+`).

 You can have several relay servers running across the globe and leverage GeoLocation to use the closest relay server, giving you a faster experience when connecting to remote computers.
