What is Markdown?

Markdown is a lightweight markup language created by John Gruber in 2004. It allows you to write using an easy-to-read, easy-to-write plain text format, which then converts to structurally valid XHTML (or HTML).

Unlike WYSIWYG (What You See Is What You Get) editors like Microsoft Word, Markdown separates the content from the visual presentation. This makes it incredibly portable and perfect for writers, developers, and content creators who want to focus on the text without getting distracted by complex formatting menus.

Why Use a Markdown Editor?

  • Speed: Format text without lifting your hands from the keyboard.
  • Portability: Markdown files are just plain text files (.md), readable on any device and future-proof.
  • Clean HTML: Generates clean, semantic HTML without the bloat of traditional rich text editors.
  • Universal: Supported by GitHub, Reddit, Stack Overflow, Discord, and nearly all CMS platforms.
