- `mermaid`: whether to enable [[Mermaid diagrams]]. Defaults to `true`
- `parseTags`: whether to try and parse tags in the content body. Defaults to `true`
- `enableInHtmlEmbed`: whether to try and parse Obsidian flavoured markdown in raw HTML. Defaults to `false`
- `enableYouTubeEmbed`: whether to enable embedded YouTube videos using external image Markdown syntax. Defaults to `false`
- Link resolution behaviour:
- Disabling: remove all instances of `Plugin.CrawlLinks()` from `quartz.config.ts`
- Changing link resolution preference: set `markdownLinkResolution` to one of `absolute`, `relative` or `shortest`
