[AlexandreAllard]

Hey, I’m a student/software developer and a big Three.js enthusiast.
I’d like to contribute by translating the documentation into French.

How should i proceed?

I will continue with the API Reference part, i will create PRs only when finishing entire parts (Animation, Audio, Camera...).

Hello there, I plan to continue to traduce the documentation with the "constants" part. I'll do a pull request once the part is done.
