I think people need to know how the vbamanager works, how to load a VBA project, how to access the macros, how to create a new module, name a module, save a project etc.
When I was starting, people would send me code or I would copy code from The Net but I didn't know what to do with it.
Once I learned how to make a Module, name it, paste the code in and save it, I was on my way.
