## What it is
A collection of hand-crafted User Defined Language (UDL) XML files that add Markdown syntax highlighting to Notepad++ across many editor themes. It ships as an npm package with a CLI (npx markdown-plus-plus / mpp) to download and install the UDL files.

## Use cases
- highlight markdown files in notepad++
- add markdown syntax highlighting to notepad++
- install a markdown UDL matching my editor theme
- enable markdown highlighting for dark mode in notepad++
- customize a markdown UDL file for notepad++
- support .md and .markdown files in notepad++

## When to choose
- you write Markdown in Notepad++ and want theme-matched syntax highlighting
- you want a simple UDL file install or an npx-based downloader
- you need dark-mode-aware highlighting on Notepad++ v8.1.3+

## When to avoid
- you use a different editor than Notepad++
- you need Markdown preview or rendering, not just highlighting
- you want machine-generated or auto-updating language definitions
