This tutorial is written in English, but you can read it in your own language using Chrome's built-in translation feature.

Chrome will translate the entire page instantly. The translation stays active as you navigate between pages, so you only need to set it up once.
Right-click anywhere on the page and select "Translate to [your language]" from the menu. You can also go to Chrome Settings → Languages to enable translation.
Chrome is smart enough to leave code blocks untranslated — so terminal commands and code snippets will remain in English, which is exactly what you want.
