Translations are provided by fans (we simply do not know russian ourselves, so we can't do it), and it requires a small group as there is a LOT to translate... if some russian fans are up for it, they are free to try.

Some devs provide something for a smoother job or prefer it being delivered a certain way, i'd join our Discord server and ask Caro himself (i also recall him being one of the devs that encrypted the text files, so might as well make it simpler for you).
Chances are translator++ will be enough, it's my fav, or microsoft visual studio 2022, all free and easy to use, but yeah, talk to him first, you can always poke me on there later as well.
