+Quartz supports the same Admonition-callout syntax as Obsidian.
+
+This includes
+
+- 12 Distinct callout types (each with several aliases)
+- Collapsable callouts
+
+```
+> [!info] Title
+> This is a callout!
+```
+
+See [documentation on supported types and syntax here](https://help.obsidian.md/Editing+and+formatting/Callouts).
+
 > [!warning]
 > Wondering why callouts may not be showing up even if you have them enabled? You may need to reorder your plugins so that `Plugin.ObsidianFlavoredMarkdown()` is _after_ `Plugin.SyntaxHighlighting()`.
 
+## Customization
+
+- Disable callouts: simply pass `callouts: false` to the plugin: `Plugin.ObsidianFlavoredMarkdown({ callouts: false })`
+- Editing icons: `quartz/plugins/transformers/ofm.ts`
