Frequently Asked Questions

What is MDX?

MDX is Markdown that lets you import and render JSX/React components inline. It powers documentation sites (Docusaurus, Astro, Next.js) because you can mix prose with interactive components while keeping Markdown’s simplicity.

Which components are available by default?

Common built-ins include Callout (admonitions), CodeBlock (syntax highlighting), Tabs, Steps, and Accordion. You can extend these in your own project; this playground ships a sensible default set.
