How to set which page opens first when app is opened?

I watched the entire tutorial on making the book app and searched the docs button cannot for the life of me figure out how to set which page opens first when app is opened. Can somebody please tell me?

Hi Daniel,
You can go to the navigation link in appgyver page, and go to the home pgae button and select the default page at the right from the dropdown list under “page”.

Hi, there is a drag and drop interface to reorder the pages:

How do I show a top navigation bar only on certain pages?
