Markdown is a markup language. It is used for creating formatted text. Its key feature is you only need a plain-text editor to write it. This is because Markdown remains readable without any rendering. Markdown is widely used for blogging, messaging, online forums, and readme files. I personally use Markdown to write this blog and take notes with Obsidian.

Below I will show all the features of Markdown.
