First time that I ever managed to comprehend anything related to this topic.
Wikipedia and ncatlab are very good websites, and yet they are bad for introduction to this topic.
This is the first video that I watched from this channel about this topic, since I believe in general case first, special case later if ever, and still managed to comprehend the definitions, even if not the motivations or the reasons for the names.
