-## 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.
+## 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) Create the project root directory, name doesn't matter.
-## 2) Inside the project root directory, clone the limboai repository:
+## 1) Clone the limboai repository:
 ##    git clone https://github.com/limbonaut/limboai
-## 3) From the project root directory, run:
-##    bash ./limboai/gdextension/setup_gdextension.sh
+## 2) From the limboai root directory, run:
+##    bash ./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, unless cloned manually.
-##   project/demo/ -- symbolic link (leads to limboai/demo).
-##   project/demo/addons/limboai/limboai.gdextension -- symbolid link (leads to limboai/gdextension/limboai.gdextension).
-##   project/demo/addons/limboai/icons/ -- symbolic link (leads to icons/).
-##   project/SConstruct -- symbolic link (leads to limboai/gdextension/SContruct).
+## 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: Symbolic links will be created by this script.
+##   Note: Script creates symbolic links unless --copy-all is set, in which case it copies the files.
 ##
-## Dependencies: bash, git, python3.
+## Dependencies: bash, git, python3, trash (optional).
