What topics should and shouldn't be included, and why or why not?

How specific should one be while explaining these topics? Should one aim for the basics, or already take it a step further and explain them on a more advanced level?

In which specific order should the topics be explained? (How would you order your topics)

Should one talk about how Bitcoin came to be? The different technological solutions and their creators, eventually leading to the creation of Bitcoin? It'd be a small lesson in history, yet also show that Bitcoin wasn't simply put together in a blink, but a product that came to be true years of trial and error and smart design.

Should one include specific events that influenced Bitcoin, and which would these be?

What properties of Bitcoin should be included, or asked otherwise; what are Bitcoin's most defining properties?

I'm not asking for a copy-paste explainery or peppy video about Bitcoin, but for a rough direction of what you would like to see come back in a solid introduction to Bitcoin, for I want to write it in my own words.
