Just monitor the cameras and use your flashlight to check the doors and the vent. The other instructions are in the game if you listen to the phone call. Try to survive until 8 AM. I also just added a generator in the new update that lets you generate power, but will momentarily disable your camera.
Thanks to Scott Cawthon for making fnaf games so some of the credit goes to him but the rooms and characters were made by me.
