+## This script creates project structure needed for LimboAI development using GDExtension.
+## Works only on Unix-likes. You can still use the directory layout below, if you are on Windows.
+##
+## Instructions:
+## 1) Create the project root directory, name doesn't matter.
+## 2) Inside the project root directory, clone the limboai repository:
+##    git clone https://github.com/limbonaut/limboai
+## 3) From the project root directory, run:
+##    bash ./limboai/gdextension/setup_gdextension.sh
+##
+## Directory layout:
+##   project/ -- call this script from here, directory name doesn't matter.
+##   project/limboai/ -- LimboAI repository should be here after you clone it.
+##   project/godot-cpp/ -- will be created by this script.
+##   project/demo/ -- symbolic link that will be created by this script.
+##   project/SConstruct -- symbolic link that will be created by this script.
+##
+## Dependencies: bash, git, python3.
