How to Use Stagefright Exploit?

Hi everybody. I just discovered stagefright exploit, I searched for tutorials but nothing's there.. I found the code but I don't know how to use it. Can someone, please, explain step by step how to do it and what am I supposed to do? I would love to learn about this.

P.S. : Does it work for android versions Jelly Bean, Lollipop and Marshmallow?

Thank y'all!
