+This plugin parses the frontmatter of the page using the [gray-matter](https://github.com/jonschlinkert/gray-matter) library. See [[authoring content#Syntax]], [[Obsidian compatibility]] and [[OxHugo compatibility]] for more information.
+
+> [!note]
+> For information on how to add, remove or configure plugins, see the [[Configuration#Plugins|Configuration]] page.
+
+This plugin accepts the following configuration options:
+
+- `delimiters`: the delimiters to use for the frontmatter. Can have one value (e.g. `"---"`) or separate values for opening and closing delimiters (e.g. `["---", "~~~"]`). Defaults to `"---"`.
+- `language`: the language to use for parsing the frontmatter. Can be `yaml` (default) or `toml`.
+
+> [!warning]
+> This plugin must not be removed, otherwise Quartz will break.
