-[Xterm.js](https://github.com/xtermjs/xterm.js) for Godot.
+Xterm for Godot.
+This is still very much a work in progress.
+Most of the credit goes to the authors of [xterm.js](https://github.com/xtermjs/xterm.js) as most of this code was taken from that project and translated to GDScript.
+
+## Demo
+
+If you are running Linux and have `which`, `bash` and `socat` installed you can run the main scene (`demo.tscn`) and it will try 
+to connect the Terminal node to your system.
+
+Otherwise you can check out the gif below:

+
+## Testing
+
+This project uses the awesome [Gut](https://github.com/bitwes/Gut) (Godot Unit Testing) plugin for testing.
+You can run the tests by playing the test scene at `res://test/test.tscn` and clicking run.
