What is Markdown?

Markdown is a lightweight markup language designed to be easy to read, write, and convert to structured formats like HTML. Created by John Gruber in 2004, it allows writers to format text using a plain-text editing approach thatโ€™s both human-readable and machine-parsable.

Core Philosophy

Readability

  • Text looks clean and understandable even in raw form
  • Minimal syntax that doesnโ€™t interfere with content
  • Focuses on writing, not complex formatting

Portability

  • Works across multiple platforms
  • Can be converted to many formats
  • Platform-independent
