Why the Russian translation of the documentation is done so hackily, only the names are translated and then not all, some pages do not exist at all, and the rest are simply not translated, I already use the documentation for a long time, I have not seen the page completely in Russian.
Maybe because no one has spent the time or the money to translate it into russian, because english is the language of the internet? 
Seriously though, learn english. It will make your life easier.
