If you have Python 3.8 or higher version installed on your OS, then you can just download tatarubook.py file in the repository and use that script. It can run on any OS that supports Python.
If you are using Windows 10 or higher version of Windows, but don't have Python installed, you can download the zip file here, unzip it, then execute tatarubook.exe to use the tool. The zip file packages all the dependencies and Python interpreter in it, so that it can be run standalone (but only on Windows).
This software does'nt need setup or installation, you can put it in any folder.
