->**🛈 Supported Godot Engine:** **4.2** (latest release) | **4.3-rc** (`master` branch)
 
 **LimboAI** is an open-source C++ plugin for **Godot Engine 4** providing a combination of
 **Behavior Trees** and **State Machines**, which can be used together to create complex AI behaviors.
 It comes with a behavior tree editor, built-in documentation, visual debugger, extensive demo project with a tutorial, and more!
 While it is implemented in C++, it fully supports GDScript for [creating your own tasks](https://limboai.readthedocs.io/en/latest/getting-started/custom-tasks.html) and [states](https://limboai.readthedocs.io/en/latest/getting-started/hsm.html).
 
-If you enjoy using LimboAI, please **consider supporting** my efforts with a donation on Ko-fi 😊 Your contribution will help me continue developing and improving it.
