 ## Note
 
-- This script does not implement logic to locate/rotate barcode in the given image.
-- Make sure the barcode image is the only thing in the image. Otherwise this script will most probably fail.
+- For best results, ensure barcode is relatively straight in the image
+- Works best when barcode occupies most of the image
