Hi! You must localize Kibana into Russian. But I can't find instructions on how to do it anywhere. All links lead to I18n. If you do not find it difficult - please explain. Thanks 
Hi,
Thanks for reaching out.
We offer supported Chinese translation in 6.7 with additional translations on the roadmap. If there is a particular language you'd like to be supported, please open a new issue for tracking purposes. If you'd like to read up on the implementation and guidelines for translating Kibana, please feel free to review our README and GUIDELINE documentation in the i18n directory.

Thanks

Currently it is not, we don't have a timeline for it as well.
