first you will need lml and Red Dead beta out of bounds
lml: https://www.rdr2mods.com/downloads/rdr2/tools/76-lennys-mod-loader-rdr/
RDB out of bounds: https://www.nexusmods.com/reddeadredemption2/mods/791
put ymaps here Red Dead Redemption 2\lml\stream
if you don't have the stream folder, create one inside lml (don't create it inside the download folder)
and install the Tumbleweed Project folder on the dowload folder of lml
