What is Astro Starlight

Astro Starlight is a documentation theme built on the Astro web framework. It provides a ready-made structure for creating documentation websites that are fast, accessible, and easy to maintain. Unlike other documentation tools, Starlight ships minimal JavaScript to the browser, resulting in faster load times and better performance.

The tool supports writing content in Markdown, MDX, and Markdoc formats, giving you flexibility in how you create your documentation. It includes automatic navigation generation, built-in search powered by Pagefind, and responsive design that works on all devices. Starlight also supports multiple languages out of the box, making it suitable for global documentation projects. The theme is highly customizable through configuration files, allowing you to match your brand while keeping the simplicity of setup.

How to Use Astro Starlight

Getting started with Astro Starlight is simple and requires just a few steps:

  • Install Starlight using the command line by running npm create astro@latest -- --template starlight in your terminal. This sets up everything automatically.

  • Once installed, start the development server with npm run dev to preview your documentation site locally in your browser.

  • Add new documentation pages by creating Markdown or MDX files in the src/content/docs/ directory. Each file becomes a page automatically.

  • Configure your site settings in the astro.config.mjs file. Here you can set your site title, add social media links, and customize the navigation sidebar.

  • Organize pages by creating folders inside the docs directory. Starlight automatically generates navigation based on your file structure.

  • When ready to publish, build your site with npm run build and deploy to any static hosting service like Netlify, Vercel, or GitHub Pages.
