Updates & Author's Notes

This is not just any book.. it's a book for authors notes! (And updates.. about my life..) Do you happen to write Author's Notes like call the chapter in your book "Author's note" well, in this. I can just name the chapter and put in Author's Note, and after I put that in, I'll say what book the author's note is for. For example: Author's Note. (Secrets- Lilla's Secret)
It's as easy as that :3 and if I wanna give updates, I can just call the chapter "Update". So ya :3
