-**Default:** `'frontmatter'`

-We parse all [YAML](https://yaml.org/) frontmatter found in code fences `---` to a named export. This is `frontmatter` by default, but can be customized using `frontmatterOptions.name`.

-For example, say you want to access frontmatter as root-level variables without a nested `frontmatter` object. You can override the [`name` configuration option](https://github.com/remcohaszing/remark-mdx-frontmatter#name) like so:
-
-```js
-// astro.config.mjs
-export default {
-  integrations: [mdx({
-    frontmatterOptions: {
-      name: '',
-    }
-  })],
-}
