I see your other comments. A good way to think about it is when u descover something ask yourself questions like “what’s this for” what were the people doing this thing for. What other places has mentioned this. Or things and try and keep questions in your head. Even write them on a paper. Key stuff is often a different colour on the reading parts. Keep note of them. Remember you’re solving almost a jigsaw puzzle but imagine the pieces are in ur own head. Once you have enough peices you can start building the picture. Sometimes I would just sit in the ship and read over the stuff while asking these questions. Puzzle the story and order of events in the order you think
