A book is a manuscript made from ordered sections. Front matter appears before numbered chapters, chapters form the main body, and back matter appears afterward. Set aside keeps material in the project without including it in the finished book.

Create a book, then add sections from its Contents page. Open a section to write its title, synopsis, status, and Markdown body. Reorder sections by moving them within or between manuscript groups. Turning inclusion off moves material out of the assembled output without deleting it.

The editor records snapshots so an earlier version can be inspected or restored. Restoring replaces the current section body, so save or copy anything you need from the current version first. Find and replace can change repeated text across the book; review the matches before applying a broad replacement.

Merging sections combines selected material. Deleting a section is different from setting it aside and should be used only when its history is no longer needed.

Plan limits apply to the number of books, not the number of chapters in an existing book. For a section whose content or order cannot be recovered from history, Contact support.
