In README.md, I found Wikimedia word. Is this typo or correct word?

HyunSoo Kim (@HyunSooKim7854) thank you for surfacing this. The cp-demo documentation is inconsistent and we should review and make it consistent.

I mean that I wanna contribute for this if possible.
Can I make PR for this?
Thanks
