Question 1

What is Markdown?

Accepted Answer

Markdown is a lightweight markup language created by John Gruber in 2004 that lets you format plain text using simple symbols. For example, wrapping a word with **asterisks** makes it bold, and starting a line with # creates a heading. Markdown is now used everywhere — GitHub READMEs, documentation, blog posts, README files, Discord, Slack, Notion, and Obsidian.
