Thanks for your interest in translating WordPress.com into Aragonese.
I've set up a new language set, so you can start translating from here right now :)
[edit: please ignore what I wrote in this paragraph, it's not accurate for Aragonese -> Once you change your interface language to Aragonese (please give us some time before it appears on the list), you can also use the Community Translator Tool.]
To get started, please check out this documentation:
and let us know if you have any questions!
