What is Markdown?
Markdown is a lightweight markup language that uses plain-text symbols — like # for headings, * for emphasis and - for lists — to format text that converts to HTML. It is fast to write, readable as raw text, and widely used for READMEs, documentation, notes and blogging.
Markdown maps simple symbols to HTML: # for headings, **bold**, *italic*, - or 1. for lists, [text](url) for links and backticks for code. The source stays readable even before rendering.
It powers GitHub READMEs, documentation sites, chat apps and static blogs. Most processors also let you embed raw HTML for anything Markdown cannot express.
