Markdown

Markdown is an open source text markup language created in 2004 by John Gruber and Aaron Swartz.

Markdown is a lightweight markup language with plain text formatting syntax. It is designed so that it can be converted to HTML and many other formats using a tool by the same name. 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. Read more on Wikipedia...
