 # Notes
 I started this project years ago with Powershell Studio using the built in deployment methods, learning Git, and learning PS best practices. So please forgive any "obvious" mistakes 😅
 Over time I have had to adjust my methods for deployment... change the design of functions, and refactor code as I learn new and better things.
