## What it is
Starlight is a full-featured documentation website framework built on top of the Astro web framework. It provides built-in site navigation, search, internationalization, SEO, code highlighting, and dark mode, with content written in Markdown, MDX, or Markdoc.

## Use cases
- build a documentation website for an open-source project
- create a docs site with full-text search and i18n
- generate a static documentation site from markdown files
- set up a fast, accessible docs site with dark mode and SEO
- add a documentation section to an existing Astro project
- write docs in MDX with type-safe frontmatter validation

## When to choose
- you want a batteries-included docs site with navigation, search, and i18n out of the box
- you are already using Astro or want its performance for a content-driven site
- you want to write content in Markdown, MDX, or Markdoc with minimal configuration
- you need to extend docs UI with React, Vue, Svelte, or Solid components

## When to avoid
- you need a dynamic web application rather than a content-driven documentation site
- you are not in the JavaScript/Astro ecosystem and prefer tools like Sphinx, MkDocs, or Docusaurus in another stack
- you need a wiki-style site with user-editable pages rather than a static build
