 ### Compiling from source
 
->**🛈 For GDExtension:** Refer to comments in [setup_gdextension.sh](./gdextension/setup_gdextension.sh) file.
-
 - Download the Godot Engine source code and put this module source into the `modules/limboai` directory.
 - Consult the Godot Engine documentation for instructions on [how to build from source code](https://docs.godotengine.org/en/stable/contributing/development/compiling/index.html).
 - If you plan to export a game utilizing the LimboAI module, you'll also need to build export templates.
 - To execute unit tests, compile the engine with `tests=yes` and run it with `--test --tc="*[LimboAI]*"`.
 
+#### For GDExtension
+
+- You'll need SCons build tool and a C++ compiler. See also [Compiling](https://docs.godotengine.org/en/stable/contributing/development/compiling/index.html).
+- Run `scons target=editor` to build the plugin library for your current platform.
+  - SCons will automatically clone the godot-cpp/ repository if it doesn't already exist in the `limboai/godot-cpp` directory.
+  - By default, built targets are placed in the demo project: `demo/addons/limboai/bin/`
+- Check `scons -h` for other options and targets.

-## This script sets up limboai project for development with GDExtension.
-## It adds missing files to the demo project for development with GDExtension, and downloads godot-cpp.
-## Tested only on Unix-likes. You can perform similar steps manually, if you are on Windows. Check Overview below.
-##
-## Instructions:
-## 1) Clone the limboai repository:
-##    git clone https://github.com/limbonaut/limboai
-## 2) From the limboai root directory, run:
-##    bash ./gdextension/setup_gdextension.sh
-##
-## Overview:
-##   limboai/ -- LimboAI repository after you clone it - call this script from here.
-##   limboai/godot-cpp/ -- git repo that will be cloned by this script, unless already exists.
-##   limboai/demo/addons/limboai/limboai.gdextension -- symbolic link created (leads to limboai/gdextension/limboai.gdextension).
-##   limboai/demo/addons/limboai/icons/ -- symbolic link created (leads to limboai/icons/).
-##
-##   Note: Script creates symbolic links unless --copy-all is set, in which case it copies the files.
