Launch the exe to set up the mod environment, you will be prompted to point at your game directory and it will create relevant files and folders. put DeS mods in the mods folder of the program. Try to put them in a way that resembles a structure like this
mod-name
- parts
- script
- param
Although the program should be smart enough to detect it otherwise by scanning deeper into sub-directories. Also supports .zip and .rar files, so if all is well it should be entirely possible to download straight into the mods folder and get to work with it.
- enabling/disabling mods.
- automatically backing up vanilla files
- saving currently enabled mods as a modpack
- refreshing mod list
- Plenty of safety checks.
It never hurts to be sure, back up files related to the selected game folder that you will be modding if you feel so inclined.
