Optional video tutorial for installing SuperBLT, BeardLib, and mod_overrides mods: https://youtu.be/rin_sjSJIkg

1. After downloading the mod, use a program such as 7zip or WinRAR to extract the main folder of the mod.
2. Drop that folder into the mods folder which is supposed to be in the game's installation folder (don't know where that is? click here)

install the map by placing the map folder (knockover_jewlery) inside the .zip archive inside PAYDAY 2/Maps.

--IF YOU'RE INSTALLING THE ADDON--
drop knockover_jewlery inside PAYDAY 2/Maps. only do this AFTER you've installed the custom heist itself or it won't do anything.
