This is probably not simple. You know how apps and some websites offer an overlay to their page with arrows and tips on how to use the site or app? I want that for my site. FTUE = first time user experience. I'd want it to be customizable so I could highlight the areas I want to educate on, and customize the associated text. It could be refreshed for all user groups when a major upgrade occurs. It could present tips one at a time (Google does this) with next/skip options or it could simply be one giant overlay with an "ok, got it!" prompt to close out. Would you use this?
