What Is Markdown?
Markdown is a lightweight markup language created by John Gruber in 2004. It uses simple text formatting conventions — asterisks for bold/italic, hashes for headings, dashes for lists — that are easy to read in plain text and convert cleanly to HTML. It's become the de facto writing format for technical documentation, README files, static site generators, and developer communication.
Markdown is used by GitHub (README.md, issues, PRs), Stack Overflow, Reddit, Discord, Notion, Obsidian, Jekyll, Hugo, Docusaurus, and countless other platforms. Learning Markdown syntax is one of the highest-leverage skills for any developer.
