What is Markdown?

Markdown is a lightweight text format that uses simple punctuation to mark up headings, lists, links, code, and emphasis. Created by John Gruber in 2004, it became the standard for README files, documentation, blog posts, GitHub issues, Reddit comments, and Stack Overflow answers. The point is simple: write in plain text that stays readable, and let the renderer turn it into well-formatted HTML.

When to use a Markdown editor

Common use cases: writing a project README, drafting a blog post for a static site generator, preparing release notes, taking structured notes, writing documentation for an open source library, formatting answers for technical Q&A, or just composing a clean text with headings and lists you can copy elsewhere.

Quick syntax reference

Headings: # H1, ## H2, ### H3 · Emphasis: **bold**, *italic*, ~~strike~~ · Lists: - bullet, 1. numbered, - [ ] task · Links: [text](url) · Images: ![alt](url) · Code: `inline` or fenced ``` blocks ``` · Quotes: > quote · Tables: | col | col | with --- separator.
