At this stage in its development, iD is using an extremely minimal, simple system for translations. This directory contains languages according to code (de: German, fr: French, etc).

To contribute:

If you're technically-minded, clone this repository and edit the necessary file, and you can preview your changes in-place if your system language is set. Check out the contributing guide for submitting changes.

If you aren't, you can still contribute! You'll still need a GitHub account, but you can just browse to your language's file here, click 'Edit', and edit each translated string.

Contributions to translations are under the same liberal license as iD itself, wtfpl.
