How to make prestashop friends with the Kazakh language?

Question

Machine translation from one language to another

I downloaded the Prestashop starter template. And for a long time I can not translate the template into Kazakh. It seems that everything was done correctly when I imported the translation, there were no errors.
My actions.
1. Create a new language (with iso code `kk`, language_code `kk-KZ`). Everything is successful.
2. Then I took the translation that was on the path `app/resources/translations/ru-RU`, since nowhere was it said where to get it.
3. I replace all ru-Ru with kk-KZ. Rename filenames.
4. I create a gzip archive called kk.tar.gz.
5. I import through the `import manually tool`. It is NOT clear why the default class is `.hide`.
6. I get a successful alert. I click on another modify translation tool. I choose a topic and then I get the error `undefined kk index` or `path not found main/kk-KZ/curriences`.
Has anyone come across this?
Thanks
