I'll do a PR with those translations if that's ok.

Awesome!

I'm adding those to the json file along with the descriptions but I can't find the French version of the website. Is it WIP?

There won't be a french version until we've finished translating the whole curriculum.

Oh, right, let's get it done then.

Thanks. Use this for chatting in future: https://gitter.im/FreeCodeCamp/TranslationFrench
