Checkout Customer Redirect or Workflow

After someone makes a purchase, I want to be able to have a custom redirect, or a workflow that gives them the next steps before they make create their account. For example, "Thanks for your purchase, here are the next steps…"

Not everyone knows the flow of online course purchases. It's easy to think they do because we are all in the industry, but it is not universal information. I want to make it clear and easy for people to understand what comes next.
