## What it is
mdsvex is a Markdown preprocessor for Svelte, essentially MDX for Svelte. It lets you use Svelte components inside Markdown files and Markdown inside Svelte components, with support for remark/rehype plugins, syntax highlighting, frontmatter, and custom layouts.

## Use cases
- write blog posts in markdown with embedded svelte components
- use MDX-style documents in a sveltekit site
- add frontmatter and custom layouts to markdown content
- apply remark and rehype plugins to markdown in svelte projects
- render interactive charts inside markdown documents
- compile markdown files to svelte components

## When to choose
- you build content-driven sites with Svelte or SvelteKit and want MDX-like authoring
- you need to mix interactive Svelte components into Markdown documents
- you want remark/rehype ecosystem compatibility in a Svelte project

## When to avoid
- you use React, Vue, or another framework instead of Svelte
- you only need plain Markdown rendering without component embedding
- you need a full static site generator rather than a build-time preprocessor
