 2. How to use:
 	a. Add custom face dataset
 		1. Open "Facial_Recognition_Registration.py".
-		2. Change string variable "label" (at line 7) to your name, such as: label = "feier_zhang"
-		3. If using the laptop camera, make sure "cap = cv2.VideoCapture(0)" (at line 19);
-		   If using the external WebCam, make sure "cap = cv2.VideoCapture(1)" (at line 19).
