+
+Remove the auto-generated `$entry` variable for Markdoc entries. To access frontmatter as a variable, you can pass `entry.data` as a prop where you render your content:
+
+```astro
+---
+import { getEntry } from 'astro:content';
+
+const entry = await getEntry('docs', 'why-markdoc');
+const { Content } = await entry.render();
+---
+
+<Content frontmatter={entry.data} />
+```
