hmmm, is this a good enough starting outline example ?
(it's a bit cliche but i mean, it's just an example of a outline)
What I recommend doing is run the story through your head like a movie, then you start plotting it down. Think of it like a brief synopsis where you take this overarching story and start breaking it down into chapters, I only add the main points I need to get to the end result. My map is basically what the overarching story will be with columns to break it into chapters, then I have a few sentences to sum up what the chapter will cover based on where the story is going. It makes consistency easier, you also want to take notes on any information you give that might be used later.
