What do a shunt do , anyway ?
I was looking at a meter and it said shunt required , Why ?

There's a slight resitance across a shunt as power goes through it that creates a different voltage on each side of it. This difference in voltage is directly proportional to the amount of current that's going through it.
So as an example, 10 millivolts (.010V) of drop across the shunt is shown on the meter as 10 amps. 20 millivolts = 20 amps, etc.
My professor liked to ask his unwitting class how many types of meters there are. His answer was one; the volt meter.
The amp meter is actually a volt meter with different markings.
