About Markdown Viewer

Markdown is the standard markup language for developer documentation, README files, wikis, and content management systems. Created by John Gruber in 2004, it has become the default writing format on GitHub, GitLab, Notion, Obsidian, Confluence, and countless technical platforms. Markdown's simplicity — readable as plain text, renderable as rich HTML — makes it ideal for technical writing.

Markdown Syntax Quick Reference

The CommonMark specification standardizes Markdown behavior across platforms. Core syntax: headings (# H1 through ###### H6), emphasis (**bold**, *italic*), links ([text](url)), images (![alt](url)), fenced code blocks (```language), blockquotes (>), horizontal rules (---), and inline code (`code`). Ordered lists use 1. 2. 3. and unordered lists use -, *, or + as bullets.

GitHub Flavored Markdown (GFM) adds: tables (| col | col | syntax), task lists (- [x] checked item), strikethrough (~~text~~), and auto-linking of bare URLs. This viewer also supports LaTeX math expressions ($...$, $$...$$), Mermaid diagrams, and syntax highlighting for code blocks.

FAQ

Can LaTeX math be rendered?

Yes! Use $...$ for inline math and $$...$$ for display math. Powered by KaTeX for fast, high-quality rendering.
