If it's directly at the beginning, then people might just look at that and nothing else and then I get a bunch of videos that don't follow what's written.
But you (with the help of eahs) make a point. With so much information to delve through, people may miss something important and mess up their video.
So instead of at the top, I'll put a recap at the end after they've read through the entire thing.
The post is as long as it is because I spent all of one night and all of the next morning getting everything together. I didn't want this to end up like my sister's MEP

gasp! You should have seen the things she got for that. I wanted to make myself very clear, but I don't know how many people have the attention span to go over every detail laid down.
It's nice to have a recap at the end to remind the reader of what they've read. If there's something in particular that they've forgotten, they can always go back up to what section they're interested in.
*edit* But alas, it's true. People might be driven away by such a long post, so there will be something at the top as well as the bottom.
