What is Markdown?

Markdown is a lightweight markup language created by John Gruber in 2004. It uses simple, readable syntax to format text that can be converted to HTML and other formats. Markdown is widely used for documentation, README files, blog posts, and technical writing because it's easy to write and read in plain text.
