Once you go to your Sandbox TestBox the black bar will have Edit, New and Options buttons. Click “New” and then select “Book/Unit” to begin creating your OER and give it a title. You can follow the same process to create a new "chapter" and a "page" in your OER.
Follow this Quick Start Guide for more in depth instructions on how to create a new Book, Chapter, and Pages.
