-**NOTE: The GDScript version of this project turned out to be very buggy and performed poorly. I have had much more success with a gdnative implementation using [libtsm](https://github.com/Aetf/libtsm) which can be viewed in the [native branch](https://github.com/lihop/godot-xterm/tree/native) of this repo.**
+**WARNING: The GDScript version of this project turned out to be very buggy and performed poorly. Therefore, it is no longer being developed or mantained. I have had much more success with a gdnative implementation using [libtsm](https://github.com/Aetf/libtsm) which can be viewed in the [master branch](https://github.com/lihop/godot-xterm/tree/) of this repo. You should use that instead.**

 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.
