This is just a simple HTML note helper, designed for folks learning HTML, CSS, and JavaScript. It enables you to take notes in HTML/CSS/JS as you learn, in order to help retain that information.
This tool requires that Node JS is installed. You can install it from their homepage here.
It also is mostly focused toward users of VS Code. It is not a requirement, but you can download it here if you'd like.
Finally, very basic terminal usage is expected just to run the single script to create new note files.
