## What it is
A Vim/Neovim plugin that renders Markdown files in a modern browser with synchronized scrolling and asynchronous updates. It supports KaTeX math, Mermaid and PlantUML diagrams, Chart.js charts, tables of contents, emojis, and task lists.

## Use cases
- preview markdown files in browser while editing in neovim
- live markdown preview with synchronized scrolling
- render mermaid diagrams from markdown
- view math formulas in markdown notes
- write documentation with instant preview
- preview markdown readme before pushing to github

## When to choose
- you edit markdown in Vim or Neovim and want a rich browser-based preview
- you need math, diagrams, or charts rendered from markdown
- you want a cross-platform plugin with no external editor dependency

## When to avoid
- you use VS Code or another editor with built-in markdown preview
- you want in-terminal markdown rendering rather than a browser window
- you need a standalone markdown converter to HTML or PDF files
