esp8266 lissen to GET, output json


i'm trying to make a connection to my router over wifi with a arduino nano board and a ESP8266 black edition. But i can not find a tutorial on how i can do this. I have found somme but they require that i connect 2 pins on the shield with eatchother (3.3V), then the shield goes off and the usb connection to.

Can someone bring me in the right direction of getting it connected?
