This is commented out. NOTE: Best if viewed in web browser if currently you are viewing this in Lepton

Based from Brad Traversy's cheatsheet. I just updated it to work for my needs.

todo:

• add toc links
• code + result or something like this https://www.markdownguide.org/cheat-sheet/
• easy separation of sections
• remove redundant stuff because it's already in https://github.com/adam-p/markdown-here/wiki/Markdown-Cheatsheet#images ???
