Starlight

Starlight is the high-performance documentation framework built on Astro: Deliver fast, accessible, and feature-rich documentation sites with minimal setup.

This is the dedicated documentation framework for Astro, engineered for speed and accessibility (A11y). It handles core requirements out-of-the-box: integrated search (Pagefind), internationalization (i18n), dark/light mode, and auto-generated navigation. Starlight supports Markdown, MDX, and Markdoc, offering TypeScript-safe frontmatter validation for content consistency. The goal is simple: You focus on writing content in your `src/content/docs/` directory, and Starlight manages the technical complexity and performance optimization, leveraging Astro's static site generation for a stellar user experience.
