The spine is generated automatically. It will display vertically from top to bottom, similar to a US-printed book. By default, the spine includes the Scrively logo, which Plus and Pro users can [toggle off](https://support.scrively.com/hc/learn/articles/1780769696-how-to-remove-the-scrively-branding-from-your-books-plus-pro). We’re working on future updates that will give you more visual control over spine customization.
