+
+## HTTP API
+
+Interactive [OpenAPI](https://alexxit.github.io/go2rtc/api/).
+
+`www/stream.html` - universal viewer with support params in URL:
+
+- multiple streams on page `src=camera1&src=camera2...`
+- stream technology autoselection `mode=webrtc,webrtc/tcp,mse,hls,mp4,mjpeg`
+- stream technology comparison `src=camera1&mode=webrtc&mode=mse&mode=mp4`
+- player width setting in pixels `width=320px` or percents `width=50%`
+
+`www/webrtc.html` - WebRTC viewer with support two way audio and params in URL:
+
+- `media=video+audio` - simple viewer
+- `media=video+audio+microphone` - two way audio from camera
+- `media=camera+microphone` - stream from browser
+- `media=display+speaker` - stream from desktop
+
+## JavaScript API
+
+- You can write your viewer from the scratch
+- You can extend the built-in viewer - `www/video-rtc.js`
+- Check example - `www/video-stream.js`
+- Check example - https://github.com/AlexxIT/WebRTC
+
+`video-rtc.js` features:
+
+- support technologies:
+    - WebRTC over UDP or TCP
+    - MSE or HLS or MP4 or MJPEG over WebSocket
+- automatic selection best technology according on:
+    - codecs inside your stream
+    - current browser capabilities
+    - current network configuration
+- automatic stop stream while browser or page not active
+- automatic stop stream while player not inside page viewport
+- automatic reconnection
+
+Technology selection based on priorities:
+
+1. Video and Audio better than just Video
+2. H265 better than H264
+3. WebRTC better than MSE, than HLS, than MJPEG
+
+## WebSocket API
+
+Endpoint: `/api/ws`
+
+Query parameters:
+
+- `src` (required) - Stream name

+# Expr
+
+[Expr](https://github.com/antonmedv/expr) - expression language and expression evaluation for Go.
+
+- [language definition](https://expr.medv.io/docs/Language-Definition) - takes best from JS, Python, Jinja2 syntax
+- your expression should return a link of any supported source
+- expression supports multiple operation, but:
+  - all operations must be separated by a semicolon
+  - all operations, except the last one, must declare a new variable (`let s = "abc";`)
+  - the last operation should return a string
+- go2rtc supports additional functions:
+  - `fetch` - JS-like HTTP requests
+  - `match` - JS-like RegExp queries
+
+## Examples
+
+**Two way audio for Dahua VTO**
+
+```yaml
+streams:
+  dahua_vto: |
+    expr: let host = "admin:password@192.168.1.123";
+    fetch("http://"+host+"/cgi-bin/configManager.cgi?action=setConfig&Encode[0].MainFormat[0].Audio.Compression=G.711A&Encode[0].MainFormat[0].Audio.Frequency=8000").ok
+        ? "rtsp://"+host+"/cam/realmonitor?channel=1&subtype=0&unicast=true&proto=Onvif" : ""
+```
+
+**dom.ru**
+
+You can get credentials via:
+
+- https://github.com/alexmorbo/domru (file `/share/domru/accounts`)
+- https://github.com/ad/domru
+
+```yaml
+streams:

+# GoPro
+
+Supported models: HERO9, HERO10, HERO11, HERO12.  
+Supported OS: Linux, Mac, Windows, [HassOS](https://www.home-assistant.io/installation/)
+
+The other camera models have different APIs. I will try to add them in the next versions.
+
+## Config
+
+- USB-connected cameras create a new network interface in the system
+- Linux users do not need to install anything
+- Windows users should install the [network driver](https://community.gopro.com/s/article/GoPro-Webcam)
+- if the camera is detected but the stream does not start - you need to disable firewall
+
+1. Discover camera address: WebUI > Add > GoPro
+2. Add camera to config
+
+```yaml
+streams:
+  hero12: gopro://172.20.100.51
+```
+
+## Useful links
