Markdown
A friendly guide to Markdown, the plain-text writing format. It covers the basic syntax, the extensions that add tables, diagrams and maths, and the best tools for every platform.
What is in it
Basics
The core syntax: headings, formatting, lists, images, links, code and quotes. Everything you need to write a complete document with nothing but your keyboard, plus a cheat sheet and a compatibility table.
Extensions
Beyond the core: GitHub Flavored Markdown, tables, task lists, footnotes, diagrams and charts, and maths.
Tools
Our own in-browser editors, converters, formatters and diagram makers, with nothing to install, alongside the best apps for every platform.
Developers
A reference for parsing and rendering Markdown in your own software.
