Currrently I have no organization. this is my first long term DND campaign and I am struggling to keep track of my shit. Vaguely titled word documents aren’t cutting it.

How do y’all reccommend I organize my world building? Are there any preformatted guides y’all would recommend? Maybe a system or organization y’all use that is particularly good? I suck at being organized lol

Edit: also how do y’all organize/write your pre-session planning?
