This is not about some sort of language leaderboard. If you see the title (as phrased) written in %language%, you’d expect the proposed thing to work in that language.

Anyway, as someone else pointed out it’s a fork, so it’s understandable if docs weren’t fully updated from upstream.

If the title were written in Mandarin I would have no clue at all what this software is about.

I too was slightly disappointed to find in the repo that this version is for Mandarin, but the amount of life time lost by clicking on a Github link does not make me want to complain about it. I got over it pretty quickly.

Speak for yourself if you experienced disappointment. I just clicked through, looked at it and left a note that technical merits aside the title is technically clickbait, that’s all.
