Add new language to the CRM (example domain: domain.com)
open CRM
Admin → Business Units → create (1 for each new language) DONT ACTIVATE IT !
set all necessary settings as per the form there - many things they can be copied from the English Business Unit
tell translators to open admin (could be the CMS-Admin with no IP restrictions)
go to Translation Summary → find THEIR language and translate everything it tells them to. Once they are done, then can check all on sandbox
Only at the VERY end, and they are happy with sandbox, they can come to us to request to make that language active. For that, Adam runs a quick SQL script (to make the pages published and to activate the business-unit)
so:
1. Create business unit, dont activate
2. Get the Excel sheets with system messages to be translated (not available in business unit)
