The home page for the package contains the package license, installation and downloading instructions, a complete listing of package contents, help for the modules, a brief description, and examples. You can probably get started using just the home page.

This manual provides details of the programming logic behind the package. Additionally, it provides a more complete and useful description of using the AtmQty class, which you'll probably want to read if you want to use the class for anything more than the most rudimentary calculations.
