What needs to be done?

A good part of it can be recycled to inform people wishing to contribute to BP translation.

But we probably need to remove the "Custom" part:

• as to my knowledge, since WP 4.6 it's no more possible to use a custom language file. I'll check it again.
• it's probably something we'd need to put into the developer handbook

This other page of the Codex is very similar: https://codex.buddypress.org/getting-started/customizing/buddypress-in-your-language/

After thinking a bit more about it, this section of the contributor's handbook is informing about all translation contributors need to know.

So let's see if we can still use what's explains the tutorial about using custom language files to eventually move this content to the users handbook.
