I have installed a payment processor extension and it is only in english by default. The vendor delivered a .po and a .mo file with a german translation of the extension. What is the best way to implement the translation of the extension? As I'm new to CiviCRM and following what i have read in the documentation i need to do it via a team on the Transifex project?
Is this the only way? Or can i do it manually as well? It is connected to a drupal CMS and i know how to translate custom modules in drupal.
Any hint appreciated!
