I'm so happy someone took the initiative to do this.
It doesn't seem to be working for me, but I'm sure I did something wrong.
I dropped the folder 'update' into the "lml" folder, which I have in "Steam>steamapps>common> Red Dead Redemption 2".
Running the Mod Manager says that the game isn't running, but in tutorials on YouTube that seems to be the way it is.
Is there any advice you can give?
