Welcome to the world of Markdown! In the next hour, you will discover why millions of writers, developers, and creators have abandoned complex word processors for this beautifully simple markup language. Markdown is not just another tool. It is a philosophy. Write once, publish anywhere. No vendor lock-in. No formatting nightmares. Just pure, portable content that works everywhere from GitHub to Gmail, Notion to Reddit. This is your complete guide to mastering Markdown.
Markdown is a lightweight markup language created by John Gruber in 2004. It allows you to write using plain text with simple formatting syntax that can be converted to HTML and many other formats.
