Remove the translations from the readme?

[bjohansebas]

This is the only package I've seen within the project that has translated its readmes into other languages. It's a great idea but requires effort to maintain, as happens with the website, where there might be content that hasn't been updated yet.

There are several PRs attempting to update this documentation, such as (#782, #1264, #1255 and a few others that exist), and they've been open for quite some time already.

So one idea would be to remove these translations for now or accept the existing PRs.
