Its dumb question lol…but how download it from phone??
At the bottom there is desktop version of the code page. Go to desktop version then click the green button that says “Clone or Download” and download as a 7zip file. Make sure you have ES File explorer. When it’s downloaded, open the file then you’ll be in ES File Explorer. Hold the file, then hit “extract” at the bottom of the screen.
Then pick choose path, go to Android>data>com.cleverraven.cataclysmdda>files>data>mods, then hit ok.
Make sure you follow mod instructions on installation, too. Like taking out a folder from the mod.
This assumes that you use android, and that your’re downloading mods.
