Use banners to display important announcements, updates, or notifications across your entire documentation site. Banners appear at the top of every page, support Markdown formatting, and can be made dismissible. To add a banner, use the banner property in your docs.json: 
"banner": {
  "content": "🚀 Version 2.0 is now live! See our [changelog](/changelog) for details.",
  "dismissible": true 
}
