Arduino + LCD?

I recently bought the Serial Graphic LCD 128x64 (with serial backpack) from, hoping to connect it to my Arduino. Unfortunately, it didn't come with instructions and the online datasheet was no help at all. What I'm looking for is something that tells me how to connect the Arduino the the LCD and what kind of commands I need to send to make it work. Any help would be much appreciated.

Did you look at the example code that they provide???
