## What it is
Markdown Preview Enhanced is an editor extension that provides a rich live preview of Markdown files with support for math (KaTeX/MathJax), diagrams (Mermaid, PlantUML), table of contents, and Pandoc export. It was originally an Atom package and is now primarily maintained as a VSCode extension.

## Use cases
- preview markdown with live rendering in vscode
- render mermaid diagrams inside markdown notes
- write math equations in markdown with katex
- export markdown to pdf or html via pandoc
- add a table of contents to markdown documents
- preview plantuml diagrams from markdown

## When to choose
- you write markdown in VSCode and want a feature-rich preview
- you need diagrams, math, and export options in one markdown previewer

## When to avoid
- you still use the Atom editor, which is discontinued
- you need only a minimal markdown preview without extra features

## Facets
- artifact type: plugin
- maturity: active
- function: markdown, documentation, pdf, data-visualization
- domain: documentation, developer-tools, text-editors, web-development
- platform: editor-plugin, cross-platform, browser
