Hegel's Phenomenology of Spirit: a Couple Questions

A few questions before diving in. I read a couple of other threads that touch on this I just want as broad of a opinion on the book as possible.
Any prerequisite books? I think I got my bases covered I am just making sure that there arent any deep cuts that im missing. What is this book trying to accomplish? What is Hegel aiming to say in this book? What are the key insights? Any standout sections? Why is it written the way it is written? Is there any terms that I should better understand that will make reading this book easier? Is there any differences between editions? I heard it was written in quite a haste. Does that mean he contradicts himself at any point throughout the book? Is there any good "cheat sheets" to better understand this book? I don't know what would be qualify as a cheat sheet but if there is any resources that helped you while starting to understand Hegel? Any good videos on Hegel that speaks in easy language that you find useful? I have been confused about the notion of Spirit itself. Is there any good videos on the subject you know of? Any other resources for further reading, as well as further reading for Hegel in Marxism. It doesn't have to be books, but college papers would do just fine.

Hegel has been a real struggle for me. Thank you so much for your time.
