Hi @Zhbert, and thank you for your first contribution!

Please note that this article is still a draft in English (the draft: true line makes it clear). I'd suggest coming back to finalising this localisation when the original text is approved & published in the English glossary :pray:

UPD: It won't leave the draft status since it became deprecated here: #1326
