How would I go about making a part follow a set of nodes using CFrame?

How can I make a part follow invisible nodes? I’ve seen many topics on this but they still don’t really make sense to me. I have no idea of where to begin. If anyone can help point me in the right direction, that would be awesome! If you have any questions, feel free to add me on Discord: happyhal75#2503 . Thank you, have a great day!
