How does Markdown Work?

You add markdown markup on content in plain text files generally having .md or .markdown extensions, and then Markdown applications convert those markdown files into HTML.

These application can be anything like Text Editors, Messengers, Static Site Generator, e-Book Generator, PDF Converter, Presentation Generator or a Command line script.

These applications use Markdown Processor (or Markdown Parser) behind the scenes which convert the Markdown files to HTML or other formats.
