Write Markdown on the left, see rendered HTML on the right — live as you type
What Is Markdown?
Markdown is a lightweight markup language created by John Gruber and Aaron Swartz in 2004. It was designed to be readable as plain text while being convertible to HTML. Instead of writing <strong>bold</strong>, you write **bold**. Markdown supports headers, lists, links, images, code blocks, tables, and blockquotes with minimal syntax that stays out of your way.
Where Markdown Is Used
Markdown is the default formatting language across the software industry. GitHub uses it for READMEs, issues, and wiki pages with their GitHub Flavored Markdown (GFM) extension. Reddit, Discord, Slack, Notion, and Obsidian all support Markdown. Static site generators like Jekyll, Hugo, and Gatsby use Markdown files for content. Technical documentation platforms like Read the Docs and GitBook render Markdown natively. Its ubiquity makes it an essential skill for developers, writers, and content creators.
