You upload your books yourself. The tracker keeps track for you: for each format of each edition, which stores you've planned, uploaded to, are waiting on, or are live in, with the store page's address and its ID for the book (such as Amazon's ASIN).
The book page shows how many of each edition's formats are live, and the edition page lists every store that sells that format in that language.
What you need: to tell the studio when you upload, and when the store puts the book live.
