 ## Usage
 
+Recommend to run SRS by [docker][docker-srs3]:
+
+```bash
+docker run --rm -p 1935:1935 -p 1985:1985 -p 8080:8080 \
+    registry.cn-hangzhou.aliyuncs.com/ossrs/srs:3
+```
+
+By default, the images is speedup by [ACR](https://cr.console.aliyun.com/repository/cn-hangzhou/ossrs/srs/images) 
+for developers in China, you can also run by:
+
+```bash
+docker run -p 1935:1935 -p 1985:1985 -p 8080:8080 \
+    ossrs/srs:3
+```
+
+Please open [http://localhost:8080/](http://localhost:8080/) if success, then publish stream by:
+
+```bash
+ffmpeg -re -i doc/source.200kbps.768x320.flv -c copy \
+    -f flv rtmp://127.0.0.1/live/livestream
+```
+
+Done! Play the following streams by players:
+
+* VLC: rtmp://127.0.0.1/live/livestream
+* H5: [http://localhost:8080/live/livestream.flv](http://localhost:8080/players/srs_player.html?autostart=true&stream=livestream.flv&port=8080&schema=http)
+* H5: [http://localhost:8080/live/livestream.m3u8](http://localhost:8080/players/srs_player.html?autostart=true&stream=livestream.m3u8&port=8080&schema=http)
+
+> The online demos and players are available on [ossrs.net](https://ossrs.net).
