Since folders can't be overwritten, you would just use your FTP program to drag and drop the 'includes' folder in the mod to the same level as the 'includes' folder in your store, namely the 'root' or top directory. The folders and files in the mod will then fall where they should.

Most mods are configured this way. Two caveats:

If the mod contains template or language files that would ordinarily be overriden in your custom template, the mod's author will generally provide folders with a generic template name (usually 'YOUR_TEMPLATE') to hold them. You need to change the name of those folders to the name of your custom template's folders.

Same thing in case the mod contains admin files. In many mods, you'll have two folders to upload: 'admin' and 'includes'. Change the 'admin' to the name you gave your admin folder before you upload the mod.
So, in other words, even though my FTP program says "Uploading 'Includes' will override the 'Includes' on your site."
IT WILL NOT BE OVERRIDDEN, BUT THE CONTENTS OF THE NEW INCLUDES FOLDER WILL BE ADDED to the existing folder?

THAT SHOULD BE EXPLAINED. it is very vague and contradicts good computer practices... Caution must be taken when one overrides a file, right?
