How to use the Markdown Previewer
What is Markdown?
Markdown is a lightweight markup language created by John Gruber in 2004. It uses plain text formatting syntax that converts to HTML. It's used for README files, documentation, blog posts, forum comments, and anywhere you want formatted text without a rich text editor.
GitHub Flavored Markdown (GFM)
GFM is GitHub's extension of standard Markdown that adds tables, task lists, strikethrough, and fenced code blocks. It's the most widely used Markdown dialect and is supported by GitHub, GitLab, VS Code, Notion, and most modern documentation tools.
Common use cases
Developers use Markdown for writing GitHub README files, project documentation, technical blog posts, API documentation, release notes, and pull request descriptions. It's also widely used in static site generators like Jekyll, Hugo, and Next.js MDX.
