Introduction😞 way to complicated for an uninitiated

Just signed up and I’ve so far read through the getting setup section and am completely stumped. It’s not to say that I can’t eventually complete the setup but undoubtedly it’s the work of days compared to what an introduction normally is. I honestly have no idea if I should press complete and continue, if I am expected to have completed the entire setup 1 to 5 before the actual topic of education begin or what. This is completely advance way beyond what I am ready for. The objective of any course instructions should be to ensure the student is guided in every way with assurance of successful attaining a learning objective before moving forward. I’ll have to use AI in the completion of setting up otherwise all the errors I will be making will demotivate me and probably lead to course failure.
