+=======
+
+Package opus provides Go bindings for Opus encoder/decoder reference implementation from [Xiph.org](https://www.xiph.org).<br />
+All the binding code has automatically been generated with rules defined in [opus.yml](/opus.yml).
+
+### Usage
+
+```
+$ brew install opus
+$ go get github.com/xlab/opus-go/opus
+
+$ go get github.com/xlab/opus-go/decoder
+(optionally if you need a quickstart in decoding)
+```
+
+Examples of usage: an implemented [Opus decoder](/decoder) for Go programming language.
+
+### Demo
+
+```
+// webm
+```
+
+### Rebuilding the package
+
+You will need to get the [cgogen](https://git.io/cgogen) tool installed first.
+
+```
+$ git clone https://github.com/xlab/opus-go && cd opus-go
+$ make clean
+$ make
+```
