## What it is
Markdig is a fast, CommonMark-compliant, extensible Markdown processor for .NET that converts Markdown to HTML. It provides a rich AST with source locations, roundtrip trivia support, and 20+ built-in extensions such as tables, footnotes, and GitHub alerts.

## Use cases
- convert markdown to html in a .net app
- parse markdown into an abstract syntax tree
- build a markdown editor with source locations
- render github-flavored markdown including tables and alerts
- programmatically edit markdown documents losslessly
- add custom markdown syntax extensions

## When to choose
- you need a spec-compliant, high-performance markdown parser on .NET
- you need an AST or lossless roundtrip editing of markdown
- you want pluggable markdown extensions like pipe tables, footnotes, or alerts

## When to avoid
- you need markdown processing outside the .NET ecosystem
- you need conversion to formats other than HTML without extra work

## Facets
- artifact type: library
- maturity: stable
- function: parser, templating, documentation
- domain: parsers, web-development, documentation, developer-tools
- platform: dotnet, cross-platform
- tags: markdown, commonmark, markdown-to-html, ast, gfm, extensible-pipeline, roundtrip
