I need to know how to configure the following wiring scenerio:

I have a 14/2 wire coming from the MAIN into the first receptacle in a finished basement room. A second wire went from this receptacle to the next receptacle. It was configured BLACK IN/BLACK OUT/BLACK PIGTAIL TO RECEPTACLE (BRASS), AND WHITE IN/WHITE OUT/WHITE PIGTAIL TO RECEPTACLE (SILVER)

I want to add a light switch to control a new light in the room. So now I have 1 line in from MAIN , 1 line out to LIGHT, 1 line out to the next recptacle and 1 RECPTACLE AND 1 SWITCH in the current double gang box.

How to configure so light can go on and off but receptacle is always HOT. (diagrams please)
