So weird that it's a Chinese title and then written in French.
It also doesn't really give much info -- the names of the items it adds, with some flavor text that doesn't actually tell what it does.
I think they copied and pasted a Google translation, perhaps mistakenly translated into French instead of English, because there's a "Introduction de l'article" in there that shouldn't be.
They also say that it's not "not open source, in my heart" and then encourage you to go to github for the source. So, I'm going to double down on Google Translate.

Looks like it adds some items, weapons n such.

wtf is this?
