i have bought my first effect pedal! wooohoooo anyway the pedal is multi effect ZOOM G2.1U, what do you say about that pedal?

and another thing.....how the hell do i use it?! ive read the manual book twice and im still not sure how to use it... i tried it myself and im messing everything up and stuff are not working the way i want them to....
so i was wondering if there is maybe an online manual? or one i can download or something that will tell me how the hell do i use it...lol
