long term eso user here, and silent follower since flarum has been announced. All I can say is bravo.
Realising there isn't any german translation yet, I'm starting to work on it right now. As far as I can comprehend, I have to download the english pack and then translate all the expressions in the folder "locale".
I'm really not sure what comes up afterwards, I have never worked with git or packagist, so when I'm "finished" with translating, I could use some advise to make my work usable for all.
Frohes Neues! (Happy new year!)
