+> :notes: Minimalist websocket framework for Go.
+
+Melody is websocket framework based on [github.com/gorilla/websocket](https://github.com/gorilla/websocket)
+that abstracts away the tedious parts of handling websockets. It gets out of
+your way so you can write real-time apps. Features include:
+
+* [x] Clear and easy interface similar to `net/http` or Gin.
+* [x] A simple way to broadcast to all or selected connected sessions.
+* [x] Message buffers making concurrent writing safe.
+* [x] Automatic handling of sending ping/pong heartbeats that timeout broken sessions.
+* [x] Store data on sessions.

+## FAQ
+
+If you are getting a `403` when trying  to connect to your websocket you can [change allow all origin hosts](http://godoc.org/github.com/gorilla/websocket#hdr-Origin_Considerations):
+
+```go
+m := melody.New()
+m.Upgrader.CheckOrigin = func(r *http.Request) bool { return true }
+```
