 # Decoders
 
-Each device model can receive a different payload, it is then necessary to decode this payload in order to retrieve the necessary information and put it in the right place in the document of the associated device.
+Since payload formats can differ among device models, it is necessary to decode each payload in order to retrieve the necessary information store it correctly in the document of the associated device.
