+An instant messaging application written specifically for the matrix protocol to take advantage of its modern features. Designed to be lightweight but not dependent on fast Internet: the state is stored locally so you don't have to wait every time you open it. Highly versatile notification options keep you informed without getting distracted.
+While it's still in early stages and far from feature-complete, the chat window has taken shape, feel free to try it out and give us feedback and feature requests.
+The project is hosted on [github](https://github.com/koma-im/koma).
