Markdown Preview

Markdown is a lightweight markup language created by John Gruber in 2004. It lets you write formatted content using plain text syntax — # headings, **bold**, *italic*, [links](url), and ```code blocks```. It's the default format for GitHub READMEs, documentation sites, blogs, and note-taking apps.

Markdown is converted to HTML for display. A heading like ## Section becomes <h2>Section</h2>. This tool renders your Markdown in real time as you type, so you can preview exactly how it will look before committing to a repo or publishing to a site.

Most Markdown parsers support GitHub Flavored Markdown (GFM) extensions including task lists (- [x]), tables, strikethrough (~~text~~), and fenced code blocks with syntax highlighting. Learning Markdown takes minutes and saves hours of fighting with rich text editors.
