[SOLVED] Language files in other languages than English

I'm using CodeIgniter to build an app for Norwegian users. If it turns out to be a success, I might launch it in more languages.

To future-proof the app, I'd like to use the language library. In system/language, however, there's only one language, English.

I haven't been able to find Norwegian language files, but I did find Danish language files (Repox/codeigniter-lang-danish).

I'm curious about CodeIgniter's policy regarding language files.

In other words, when I make Norwegian language files, how should I contribute them? Should I make my own repository on GitHub like Repox did, or is there a more official way of contributing?
