Markdown is a lightweight markup language that uses plain text formatting syntax to create formatted text. It's commonly used for documentation, README files, blog posts, and formatted text that can be easily converted to HTML.
This tool supports standard Markdown features including headers, bold and italic text, lists (ordered and unordered), links, images, code blocks, blockquotes, horizontal rules, and inline code. It uses the CommonMark specification.
