I want to translate Trisquel in Greek.
Hello,
I am a student from Greece and would like to help translate Trisquel in Greek.
I don't know of any programming language, and I'd like to know what's the procedure of doing it.
Ok I apologize because I haven't noticed Trisquel already exists in Greek...
Trisquel is a GNU/Linux distribution, a set of software that upstream projects develop. Each piece of software may or may not be (fully) translated in Greek. You should propose your help to such a software project. That said, the Trisquel project actually needs translators for its website, its release announcement, its installation slideshow, etc.
Thanks for the clarification. How do I contribute?
To the Trisquel project? That starts here: https://gitlab.trisquel.org/users/sign_up
As Magic Banana said, each project handles their own translations. You could try asking the Translation Project's greek team for info.
I suggest you start finding out an (un|mis)translated text, and going through the project's homepage. Translations are very fragmented, but it's usually either a PO file, or a web translation service.
