Starlight

Starlight is a documentation theme for Astro, so it runs inside an Astro project and does not work as a standalone tool. It accepts Markdown, Markdoc and MDX pages and adds a documentation layout, built-in Pagefind search and multilingual routing with fallback content, including right-to-left languages. A new project is created from a template, and an existing Astro project can add the theme with one command. Pages are pre-rendered by default, and on-demand rendering needs an Astro server adapter. The Astro team maintains it, and the manual setup guide covers adding it to an existing project.

Worth knowing

Build, Node.js and hosting come from Astro, so the Starlight documentation points to Astro’s deployment guides instead of listing its own targets.
