When you run the game and are greeted with the launcher. Navigate to the options icon (the gear icon) and ensure that "Enable Mods" is turned on. This is for REDMod to initialise
If all goes well and the game boots then you will likely be greeted by Cyber Engine Tweaks asking you to select a keybind to open its menu. I use "Home" but you can use whatever key you wantÂ
There will be 3 locations for tinkering with some of the mods in the guide
Cyber Engine Tweaks - Open with your keybind
Mod Settings - In the main menu
Mods - In the main menu
The mods should already be setup but you can tinker around with them if you want to change some things
