What is Markdown ?
Markdown is a way of writing that allows everyone to write HTML without even realizing it. Created in 2004 by John Gruber, the latter wanted to provide non-programmers a way to write easy to read text that would be translated into HTML.
What are the advantages?
The goal is to Markdown format easily and efficiently text using only the keyboard. It’s easy, fast and accessible to all. Write this way is useful on some forums as Stack Overflow, Reddit, Github, or to write articles with Jekyll! WordPress also allows you to write with some Markdown since version 4.3.
You can also create and edit or .markdown .md files, which are the proper extension to the files written in markdown.
