# Getting Started Welcome to the guide. This content comes **after** the frontmatter block. The frontmatter above is parsed as YAML key-value pairs separated from the Markdown body by the opening and closing `---` delimiters.

What is Markdown frontmatter?

Frontmatter is a YAML block at the very top of a Markdown file, delimited by --- on its own line at both ends. Static site generators like Hugo, Jekyll, Gatsby, and Astro use frontmatter to define page metadata — title, date, author, tags, draft status, and more — without mixing metadata into the content.

This parser handles the most common YAML subset: strings, numbers, booleans, null, and flat arrays. For full YAML parsing see YAML to JSON. To format Markdown content see Markdown Previewer.
