What do I title this course?

Hi all. I am creating an on-demand eLearning course that covers EVERYTHING about a software system. It is to take the place of a multi-day VILT. There will be introductory info to start - foundational knowledge and background stuff. I will cover the very basics of the software - the layout of the interface, core terms and functions. And then the course will move on into more advanced topics.. some rather complex. Some not everyone will have to view, based on their role.. I had to give it a name for tracking purposes and just called it "(Software System) 101," but I really don't love that, as some content will be advanced. My brain is so taxed, I cannot come up with anything better. Please help!
