## What it is
A Swift package for parsing, building, editing, and analyzing Markdown documents, backed by GitHub-flavored Markdown's cmark-gfm implementation. It exposes an immutable, thread-safe, copy-on-write markup tree similar in design to SwiftSyntax.

## Use cases
- parse markdown into a structured syntax tree in swift
- programmatically edit or transform markdown documents
- analyze markdown document structure
- build markdown documents from code
- work with github-flavored markdown in a swift app

## When to choose
- you need a spec-compliant GFM parser in Swift
- you want a typed, immutable syntax tree for markdown manipulation
- you're building Swift tooling like documentation generators or linters

## When to avoid
- you need markdown rendering to HTML out of the box with no tree manipulation
- your project is not in the Swift ecosystem
- you need CommonMark extensions beyond the supported dialect

## Facets
- artifact type: library
- maturity: stable
- function: parser, markdown, developer-tools
- domain: parsers, documentation, developer-tools
- platform: cross-platform, cli
- tags: markdown-parser, cmark-gfm, swift-package-manager, syntax-tree, document-editing, swift
