GitHub Flavored Markdown (tables, task lists, strikethrough), footnotes, front matter and syntax-highlighted fenced code blocks are supported. Generate a table of contents with heading anchors, sanitize with DOMPurify, and export as a fragment, a styled standalone document (GitHub light/dark), JSX, or print it.
