Hey, @denisbalyko. Thanks for submitting this!

I haven't decided yet if I wish to support multiple translations of this document within this repository. The issue here is that translations to other languages will be dependent on the contributors so they may get behind if I decide to make an adjustment and there's no one I know who speaks Chinese or Portuguese, etc. to reflect those adjustments in respective translations.

That being said, I do welcome translations that people create as a fork. I think it's more sustainable than distributing translations within the repo. I think I should consider adding links to translations to other languages in the README.md instead.

What do you think about this?

I think I should consider adding links to translations to other languages in the README.md instead.

I think it's a good alternative.
