New to Holga 120N

[white]

hello I just got my holga at last but realised at home I needed to ask-I've never really used film before, and its a 120- do I wind it everytime I take a picture? Because I got the film loaded the shop etc. but when I press the shutter it stays at one?

And do I wind it with the one on top of the camera or the one at the back.
sorry for the ignorance

Yes, you need to wind it after every shot, unless you want multiple exposures on the same frame (which produces interesting results -- try it). The winder to advance frames should be on the top of your camera, usually on the right side. Wind until you see the next number in the red window on the back of the camera.
