Nikon d7000/ SB 700 configuration

I'm just wondering, I have the Nikon D7000 and I want to get the SB700 to use off camera. How do I configure these so that I can use the flash off camera wirelessly?

You need wireless triggers like a Pocketwizard. Its not that cheap but they work great and you can string multiple flashes together if you want to.

This is covered in the manuals for both the camera and the flash. The camera can control the flash directly, using the pop-up flash on the camera.

You don't need Pocket Wizards, unless you are looking at long range wireless control, or need to put the flash out of the range or line of sight of the pop-up flash.
