What is Markdown?

Markdown is a lightweight markup language created by John Gruber in 2004. It uses simple text formatting syntax that can be converted to structured HTML. Markdown is widely used for writing documentation, blog posts, README files, and is loved by developers for its clean and readable format.

Common Syntax

  • Heading - Use # symbols for headings, number of # indicates heading level
  • Bold - Use **text** or __text__ for bold
  • Italic - Use *text* or _text_ for italic
  • Link - Use [display text](URL) to create links
  • Image - Use ![alt text](imageURL) to insert images
  • Code - Use backticks ` for inline code, triple backticks for code blocks
  • List - Use - or * for unordered lists, numbers for ordered lists
  • Quote - Use > symbol for blockquotes
