Markdown Guide
A clear reference for learning Markdown syntax and web writing.
Markdown Guide is a web handbook for learning Markdown, from first steps through detailed syntax lookups. It covers core formatting, common extensions such as tables and fenced code blocks, plus cheat sheets, hacks, tools, a book, and open-source project links.
Why it stands out
- Covers both original-style Markdown basics and widely used extended syntax in one place.
- Useful for both beginners and experienced users because it pairs tutorials with quick-reference pages.
- Open-source project with permissive reuse terms, making it more transparent than many one-off tutorials.
- Includes practical extras such as hacks and tool references, not just syntax definitions.
Good to know
- It is an instructional reference, not a built-in Markdown editor, previewer, or publishing workspace.
- Extended Markdown features are not supported uniformly across every app, so examples should be checked against the renderer you plan to use.
Under the radar: When a Markdown app lacks a formatting feature, check the Hacks section for fallback approaches before assuming you need a different editor.

Writers, developers, and documentation teams can quickly verify Markdown syntax while drafting web-ready text. Learn the basics before writing README files, blog posts, documentation, or notes. Look up how to format links, lists, code blocks, tables, and other common elements. Check which features are part of basic Markdown versus extended Markdown. Use the cheat sheet as a fast reference during editing or publishing.

Technical Notes
- The site links to a public API for structured access to Markdown Guide content; endpoint and usage details should be checked on its API page.
