Getting started with baldur's gate 3 mods

Since patch 7 there's a mod manager built into the game, right on the main menu. Start there. It sorts load order for you and is fine for most of the simpler mods. Once you want the bigger stuff you'll end up with BG3 Mod Manager and the Script Extender - the mod page usually says if it needs either. Back up your save before adding anything, and don't pull mods out halfway through a playthrough. That's where most broken saves come from.
