 __Notes:__
 - You can use the mod with [killap's Unofficial Patch](https://github.com/BGforgeNet/Fallout2_Unofficial_Patch), other modifications or even vanilla game.
 - NPC armor is **included** in [killap's Restoration Project](https://github.com/BGforgeNet/Fallout2_Restoration_Project). If you use RPU, you don't need to download this mod separately.
-- The mod is preconfigured for Fallout 2 (see `mods/npc_armor.ini`). It'll work with other games based on F2 engine, but that might require tinkering with the config.
+- The mod is preconfigured for Fallout 2. To work with other games based on F2 engine, it'll require additional configuration in `mods/npc_armor.ini`, and [`critters.lst`](https://github.com/BGforgeNet/Fallout2_Restoration_Project/blob/master/data/art/critters/critters.lst) (which might not be the task for the faint of heart).
