Fish Tank Background Installation

Fish Tank Background Installation?
I just bought a background for my 10 gallon tank. The problem is, I DON’T KNOW HOW TO INSTALL IT?!?!
Do I use tape?
How do I make it stick and stay to my aquarium?
P.S It is a glass aquarium!
Oh, I thought all I needed to do was peel something off…
Thanx to all!
Just tape it to the back of your aquarium. remember to tape it to the outside back, there’s no point putting it in the aquarium.
