#### Request a New Language

Let's say that you want to request translations for a language that is not yet translated, not even some pages. For example, Latin.

* The first step would be for you to find other 2 people that would be willing to be reviewing translation PRs for that language with you.
* Once there are at least 3 people that would be willing to commit to help maintain that language, you can continue the next steps.

At the same point, you try to trigger the autocomplete with `Ctrl+Space` and you see:

With that, you can scroll, seeing the options, until you find the one that "rings a bell":
