As I am contemplating writing a book, I realize I don't really know the first thing about writing a book. Like if I write it in Word, how do I set that up for basic formatting?

Also this isn't a narrative with plot, characters, etc. Even outlining isn't looking good, because I know as I write I will be adding things, moving them, etc.

I think I just have to start writing. I can write an essay, so maybe I will start there.
