 ## Clapperboard limitations
 
+The values may not always be correctly identified by the detection algorithm. Here are some limitations:
+
 - The titles of the fields appearing on the clapper board are optimized to identify the most popular fields appearing on top of clapper boards.  
 - Handwritten text or digital digits may not be correctly identified by the fields detection algorithm.
-- The algorithm is optimized to identify fields categories that appear horizontally.  
-- The clapper board may not be detected if the frame is blurred or that the text written on it can't be identified by the human eye.
