Good. But Confusing!

I want to know how to add pics and how to trim in the middle but not the begging. I wish this app would give you directions this would make it a whole lot better. Better quality maybe to. But this app is confusing and I wish I knew how to use it it would be very great if I knew how! PLEASE READ!!!
