One is mostly a list of examples of apps that have integrated; the other has a table of contents for the developer guide.
Have you tried reading past the first couple of paragraphs?
Yes. One's a summary, one's detail about the exact same subject for discussion - developer information for a just announced product that nobody can use for a few months.
All I'm hearing is you aren't able to discern the difference. Everyone else has so I think we can safely put a pin in this.
My first comment is significantly upvoted, so happy to agree to differ and put a pin in it.
