Frontmatter
Any Markdown file that contains a YAML frontmatter block will be processed by gray-matter. The frontmatter must be at the top of the Markdown file, and must take the form of valid YAML set between triple-dashed lines. Example:
---
title: Docs with VitePress
editLink: true
---
Between the triple-dashed lines, you can set predefined variables, or even create custom ones of your own. These variables can be used via the special $frontmatter variable.
Here’s an example of how you could use it in your Markdown file:
---
title: Docs with VitePress
editLink: true
---
# {{ $frontmatter.title }}

Alternative frontmatter Formats

{
  "title": "Blogging Like a Hacker",
  "editLink": true
}
