Documentation/Tools/SCS Workshop Uploader/Workshop mod structure
The standard mod is a single package with manifest.sii file inside, description and icon files and the mod data files. The Workshop mod can and should consist of many packages - this change gives you possibility to create mods that are supporting few game updates without need to activate different mod by your mod users. In the versions.sii file you specify which package game should use when using the specified game update. But remember - this layout is only correct for Workshop mods. Standard mods are still using the one package approach.
