Markdown & GitHub Flavored Markdown Explained

Markdown is a lightweight markup syntax that converts plain text into structured HTML.

GitHub Flavored Markdown (GFM) extends the syntax with tables, checklists, autolinks, strikethrough, and fenced code blocks.

This tool adds KaTeX-based LaTeX math, syntax-highlighted code, footnotes, and details/summary toggles while sanitizing unsafe HTML for safety.
