 ##### Generate files
-- Copy and modify some files (library_name = 'scripts')
-  - By script
-    - With cmake
+Once per project, need to copy/modify some files (library_name = 'scripts', for example)
+  - `.gdextension` file
+  - `register_types.cpp`
+  - `register_types.h`
+
+Don't worry, you will still be able to add custom code to this files after configuring
+
+- By script
+    - With Python
     ```bash
     # Usage:
-    # cmake -P external/cppscript/cppscript-configure.cmake <library_name> <src_dir> <project_dir>
