How to set up the onboarding guide and remove pre-set ones from google?

  Hi Guys, Sory I again am trying to build an onboarding resource tool where when new joiners start they can log in to this system and be able to understand how to set up their account and other applications. However, I am unsure of how to remove the pre-set ones which google showed as an example and how do I put in my own course and guild?  Thank you in advance
