+Why Markdown format? Markdown is a lightweight markup language with plain text formatting syntax created by [John Gruber](https://daringfireball.net). It is designed so that it can be converted to HTML and many other formats using a tool by the same name.[8] Markdown is often used to format readme files, for writing messages in online discussion forums, and to create rich text using a plain text editor. As the initial description of Markdown contained ambiguities and unanswered questions, many implementations and extensions of Markdown appeared over the years to answer these issues.
