 If you intend to target both building as a GDExtension and as a module using godot repo, you can generate compatibility includes that will target either GDExtension or module, based on the GODOT_MODULE_COMPAT define.
 
-If you want such a thing built, when running the build command, `scons`, make sure you have a file called `output_header_mapping.json` at root level of this repo. This file needs to have the mappings from `godot` repo. The mappings can be generated by running the compat_generator.py script.

 git clone godotengine/godot
 python compat_generator.py godot

+The first argument of `compat_generator.py` is the folder where the godot repo is. If this folder is not given, the current directory is assumed to be the godot repo.
+
 Then run the SConstruct build command as usual, and in the `gen/` folder you will now have a new folder, `include/godot_compat` which mirrors the `include/godot_cpp` includes, but have ifdef inside them and either include godot header or godot_cpp header.
