Info 2 [Q] Need help. Need to know how to add files through twrp.

So I have a rooted Samsung Galaxy S4 (SGH-M919V) Wind mobile Canada and I decided to get Cyanogenmod 10.2 but got the gapps for 10.1 and I have no keyboard so I cant set it up to add them manually. I wanted to know how I could add the gapps for 10.2 through twrp recovery and the computer. Please help I've had the phone for a week and I am scared to tell my dad anything!

Edit: I learned to use ADB sideload after countless hours of what to do.
