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)

3. Move the "Skill Tree Background Restoration" folder of the mods folder.
   3.1. If you don't have the mods folder on the PAYDAY 2 main folder, you'll need to install SuperBLT.

4. Move the "Nekopara Skill Tree" folder on "assets > mod_overrides".
   4.1. The assets folder is supposed to be in your game's installation folder (don't know where that is? click here).
   4.2. If "mod_overrides it isn't there, just create it and continue.
