# AI notes: heading levels must be consecutive

[//]: # (excludeFromIndex)

When editing repository documentation:

- Use heading levels in order: `#`, then `##`, then `###`, and so on.
- Do not skip levels, for example `#` directly to `###`.
- Keep the heading tree balanced inside each document; sibling sections should use the same level.
- If you add a subsection and the parent is `##`, the child must be `###`.
