How to get into a specific game was the plan here.

I've looked around a little but I've been unable to find anything that jumped out at me as particularly stellar example, so I was hoping someone here could recommend something that came to mind when they thought about it.

Hello! I'm getting into speedrunning a niche title, and was planning to make a guide for it in case anyone wanted to follow me afterwards, could someone recommend some high quality guides on this site so that I can see what I need to include and also learn general formatting stuff?
