Have a description/help tab on most selections.

If I am unsure what a button does, the only way to look it up is watch endless youtube videos or wait for someone to tell me during work hours from support. Just have a hover over feature that gives you further information about the button or section

Also just get a written help guide. And if you have a help guide, instead of telling people 10 steps to get to a button, just let them click on it and go direct to the spot they are searching for
