@it-service-npm/remark-heading-adjustment Remark plugin helps to adjust headings depth in markdown file.

When processor.data().topHeadingDepth is specified, this plugin adjusts all headings so that the depth of the top heading aligns with the given value.

This plugin can be used for dynamically change headings depth. Example: https://github.com/IT-Service-NPM/remark-include/blob/649937ef3eb87bc1b0f3bbe8e4a9a47509aba5fc/src/index.ts#L214C1-L226C1

The plugin also exports a preset called remarkAdjustTopHeadingToH1. This preset includes the remarkHeadingsAdjustment plugin with settings {topHeadingDepth: 1}.

These are meant for use in .remarkrc files and help normalize the depth of the top-level heading.
