Markdown Documentation (.markdown)
Markdown is a lightweight markup language with a plain text formatting syntax, primarily used in Markdown documentation files with the MD extension. Created by John Gruber and Aaron Swartz in 2004, it allows IT professionals to easily format text for web pages, readme files, and technical documentation. Markdown's simplicity and readability make it ideal for collaborative projects and version control systems. Its syntax is designed to be readable without compromising the document's formatting when rendered as HTML or other web formats.
