Installation:

The RampageFiles folder contains xmas props.
The lml folder contains the main mod.

Place the "RampageFiles" and "lml" folders in the game folder.

The mod requires:
ScriptHookRDR2 (I recommend using V2, which can be downloaded from Nexus)
ASI Loader (I recommend Ultimate ASI Loader by ThirteenAG, which you can download from GitHub)
Lenny's Mod Loader RDR (Downloadable from rdr2mods.com)
