+nheko
+----
+
+The motivation behind the project is to provide a native desktop app for [Matrix] that
+feels more like a mainstream chat app ([Riot], Telegram etc) and less like an IRC client.
+
+#### Features
+
+Most of the features you'd expect from a chat application are missing right now
+but you can of course receive and send messages in the rooms that you are a member of.
+
+#### Requirements
+
+Building instructions for OSX and Windows will be added.
+
+##### Linux
+
+- Qt5
+- CMake v3.1 or greater
+- GCC that supports C++11.
+
+###### Arch Linux
+
+```bash
+$ sudo pacman -S qt5-base cmake gcc
+```
+
+#### Building
+
+Run `make build`. The `nheko` binary will be located in the `build` directory.
+
+#### Contributing
+
+Any kind of contribution to the project is greatly appreciated. You are also
+encouraged to open feature request issues.
+
+#### Screens
+
+Here is a screen shot to get a feel for the UI, but things will probably change.
