Mods with installers have a very different file structure and I cannot know what you would like to install. So you need to install it through your mod manager and use the resulting installation.

Instructions

This guide assumes that you use Vortex as mod manager.

• Install the mod through the usual means.
• Right click the mod in the Mods page and click on the Open in File Manager option.
• Go up and copy the folder the files are contained inside.
• Paste this folder in the mods folder for source merge or mods-merge folder for merge mods.
• Rename it according to your naming scheme.
• Remove the mod from Vortex.
