 # proxy-go
 
-A RTMP/SRT/WebRTC/WHIP/WHEP/HLS/HTTP-FLV proxy for media server.
+An common proxy server for any media servers with RTMP/SRT/HLS/HTTP-FLV and 
+WebRTC/WHIP/WHEP protocols support.
 
 ## Usage
 
-See [SRS Origin Cluster](https://ossrs.io/lts/en-us/docs/v7/doc/origin-cluster) for details.
+This is a common proxy for all media servers, to enable you to build a Origin Cluster 
+for your media server.
+
+However, SRS works with this proxy much better than other media servers, as the proxy
+can discover more details from SRS. And this proxy is the official solution to build 
+an origin cluster for SRS. Please see [SRS Origin Cluster](https://ossrs.io/lts/en-us/docs/v7/doc/origin-cluster) 
+for details.
