Chapter 2 is expected to be released on September 25.
I edited the article with small changes and added the areas you can visit in the chapters. The page isn't yet final until UnderHeat's first POV finishes.
After UnderHeat (Frisk's POV) finishes, Asriel will be next.
Then Flowey, Froggit, and finally Sans.
Only Frisk's POV will have the route branches, as it will be too much and stop making sense with the others.

I decided the designs and other POVs are for the community to decide. It IS a community-shared au, after all.
