 Chrome/Firefox/Safari
 
 ## Usage
-- Clone the repository, run `npm install`.  
-- Run `npm start` and open https://your_sever_ip_or_domain:8086 to use html5 demo. 
-- If you need to test mobile app, please check the [webrtc-flutter-demo](https://github.com/cloudwebrtc/flutter-webrtc-demo). 
+- Clone the repository, run `make`.  
+- Run `./bin/server-{platform}-{arch}` and open https://your_sever_ip_or_domain:4443 to use html5 demo.
+- If you need to test mobile app, please check the [webrtc-flutter-demo](https://github.com/cloudwebrtc/flutter-webrtc-demo/tree/golang). 
 
 ## Note
 This example can only be used for LAN testing. If you need to use it in a production environment, you need more testing and and deploy an available turn server.
