Nexus Mods and Vortex
In an effort to make it easier to look for and install mods, I've started uploading mods to Nexus Mods and also submitted a game extension to support the game using Vortex, their mod manager.

Creating mods that are compatible with Vortex and the game extension
The game extension supports three kinds of mods: basic pak mods, UE4SS Lua mods, and UE4SS Blueprint mods. All mods must be inside a .zip file.
If these are followed, your mods should be handled by the game extension just fine.
Note: Only these types of files will be extracted from the mod zip: .pak, .txt, .dll, .ini, and .lua.
.pak mods
Simply put your .pak files inside the .zip file, in the root.
UE4SS Lua Mods
Ensure that the .zip file contains at least the following:
Mods/modname/Scripts/main.lua
Mods/modname/enabled.txt
UE4SS Blueprint Mods
Similar to the .pak mods, except that it must be placed inside a LogicMods folder.
