What is Markdown?
Markdown is a lightweight markup language created by John Gruber in 2004. It lets you format text using simple, readable syntax that converts to HTML. It is the standard format for README files on GitHub, GitLab, and Bitbucket, and is widely used in documentation, blogging platforms, and note-taking apps.
