Markdown Cheat Sheet

Markdown is a simple way to write and format text. It lets you create nicely formatted text without the use of complex coding. The idea is to make it easy for people to read and understand the formatting, even if they're looking at the raw text.

Markdown document file names use the extension “.md”.

This cheat sheet will go over some of the key components of markdown. This blog uses Markdown, so I need to keep this handy!
