Adjusting Numbering Depth on TOC

[pancakereport]

I'm upgrading UC Berkeley's Data 140 textbook from JB1 to JB2 and would like to keep numbering consistent.

With JB1, we have two main sections of the textbook: "Introduction" and "Chapters". There's numbering within "Chapters" that starts at 1. See screenshot.

When I upgraded to JB2, I was able to recreate this structure and got close to the original numberings, but because the chapters are inside of a main section, the numbering starts with the number of that section (0). So each chapter is 0.N instead of just N. See screenshot.

Do you have any suggestions for getting rid of the 0's? Is this currently possible?

Thank you for your help.

@fwkoch any ideas?

Add in frontmatter at the page:

---
numbering:
  title: 
    offset: 0
---

restart numbering? Then create a new folder with the source files there.

Yes, thanks @FreekPols!

To expand on this, I left numbering.title out of the project frontmatter. for my depth = 0 sections I explicitly set numbering.title to false (but I think this may not be necessary, it's just helpful for me to think about it this way). For the first level of title numbering/depth = 1 sections (i.e. N), offset: 0 is the correct choice. The next level of numbering (i.e. N.N) gets offset: 1 and so on..

Example that was shared with me (more complex numbering and nesting): https://github.com/FreekPols/Mechanica
