Seven flavors

Default, GitHub, CommonMark, Slack, Telegram, MultiMarkdown, and Pandoc - selected with a single Flavor enum.

Spec-compliant round-trips

CommonMark and GitHub Flavored Markdown round-trip at 100% against canonical cmark-gfm; MultiMarkdown and Pandoc verified against canonical pandoc.

Extensible

Plug in custom readers, alias tags, or transform the Markdown DOM directly via Parse/Render.

Broad framework support

Targets netstandard2.0, net8.0, net9.0, and net10.0 - runs on .NET Framework 4.6.1+, .NET Core 2.0+, Mono, and Unity.

Trimming & Native AOT ready

The default conversion path uses no reflection, so it publishes clean under trimming and Native AOT. Add custom readers with RegisterReader. CI fails on any trim/AOT warning.
