Is there Russian documentation for Ruby?

Question

ruby

Hello. I decided to keep up with the development and study the much-praised RoR, but first I decided to teach Ruby a little. The strangest thing is that I found Russian documentation for RoR, but not for Ruby.
Can anyone provide links to Russian materials on Ruby?
> Yes, I know that I need to learn English, etc., of course, I know English in some sense, but not at such a level that it would be easy and without questions to learn a new language relying only on English documentation.

Answer 1

I can advise the materials that were used in my university
