Complete Guide to Markdown

What is Markdown?

Markdown is a lightweight markup language created by John Gruber in 2004. It allows you to write using easy-to-read, easy-to-write plain text format, which then converts to structurally valid HTML. Markdown is widely used for documentation, README files, forum posts, and content management systems.
