+> :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.
