In your Mintlify project, add the following to the frontmatter of your page:

// pages/introduction.mdx
---
title: 'Introduction'
description: 'Learn how to use our platform'
'og:image': 'https://mosaicimg.com/use?url=yourwebsite.com/your_slug'
---

Remember to replace the placeholder value (like 'yourwebsite.com' and 'your_slug') with your actual website URL and slug.
