So I'm fairly new to modding and have run into my first problem that YouTube wont solve. I just downloaded the 2018 Dodge Challenger SRT Demon mod from 5mods and I don't know how to install it. The read me doesn't have any instructions, nor does the description, and the folder just has a readme file and a "2018 Dodge Challenger SRT Demon 1.4.oiv" file. I have no clue what to do with this file as all the other cars I have installed gave me instructions and were different file types. I am confused, please help lol.
