What Is Markdown?

Markdown is a lightweight markup language used to format plain text. Instead of clicking buttons like in Word or Google Docs, you use simple text symbols to control formatting such as headings, bold text, lists, and code blocks etc.

Markdown was created by John Gruber in 2004 to make writing on the web easier and more readable.

Example:

# This is a Heading. 

**This text is Bold**
