You will need to install ruby.
To run it for your mod:
ruby bin/import_data your_mod_name "path/to/hoi4/game" "path/to/your/mod"
If it works, it will generate data/your_mod_name.json
.
If it doesn't work, it should give you error message, usually listing file that caused problems.
The importer tries to figure out everything from game files, but it might need some help.
