What is Markdown?
Markdown is a lightweight markup language created by John Gruber and Aaron Swartz in 2004 as "easy-to-read, easy-to-write plain text format." The original design goal: text that's readable as-is in any editor, then convertible to HTML when needed. Twenty years later, Markdown is the dominant format for technical writing on the web.
Why Markdown won
HTML is verbose. Word processors are heavyweight. Markdown hits the sweet spot — minimal syntax, readable raw, fast to type, and convertible to HTML/PDF/anything via tools like Pandoc. It's plain text, so it works in any editor, version controls cleanly with Git, and never gets corrupted.
Where Markdown is used
- GitHub / GitLab / Bitbucket — README, issues, PRs, comments
- Notion / Obsidian / Logseq / Bear — note-taking apps
- Discord / Slack / Microsoft Teams — message formatting
- Stack Overflow / Reddit / Hacker News — comments and posts
- Jekyll / Hugo / Astro / Next.js MDX — static site generators
- Documentation tools — MkDocs, Docusaurus, GitBook
- Pandoc — convert Markdown to PDF, Word, EPUB, etc.
