Thank you for taking the time to provide these translations :)

Before I merge this in, do you mind moving the english translations back out, instead of having them in /en? This causes the default version of the docs to have a /en in the URL, which I'd like to avoid if possible. To fix this, it would be better to use a root locale for the english translation instead.

Ok, I have moved en to root, now the default document URL does not contain /en
