In Vellum, your chapters are automatically numbered. Numbering settings control how this numbering is performed.
Select Numbering from the Chapter menu to display the settings for your book:
Numbering Across Parts, Volumes
If you’ve organized your chapters into Parts, or you are making use of Volumes to create a Box Set, you can make use of the Reset across options for these elements.
The Reset across options control whether chapter numbers continue or reset across each Part or Volume:
Note: this only affects chapters that are grouped within a Part or a Volume. If you’re not seeing a change, make sure your chapters are correctly nested within a Part / Volume, as seen in the screenshots above.
By default, the first chapter of your book will be Chapter 1.
You can change Initial chapter if you’d prefer a different first chapter number, like if you are producing a separate volume that begins on a later chapter.
