Welcome to the wiki! Personally, I love this community; almost everyone you'll meet is friendly and welcoming, especially in our Discord server. For lore, there's not much you'd really need to get up to speed; I would, however, recommend you give a couple of these pages a read: Level 0, Basics of the Backrooms, and List of Canons. Those are some of the quintessential pages to understand the lore here - other than that, feel free to explore as you wish!
