Markdown is a lightweight markup language that lets you format plain text documents using simple syntax rules. It was created to be both human-readable in raw form and easily convertible to HTML for display on the web. Markdown is used everywhere — from README files on GitHub to blog posts, wikis, and documentation.
With syntax for headings, bold/italic text, lists, links, images, code blocks, and tables, Markdown keeps things clean and minimalist. Its simplicity makes it perfect for writers, developers, and anyone who needs structured, styled documents without complicated tools. This cheatsheet covers all the core syntax you’ll need to write and format Markdown files like a pro.
