+# simple script to get a vehicle fingerprint.
+
+# Instructions:
+# - connect to a Panda
+# - run selfdrive/boardd/boardd
+# - launching this script
+#   Note: it's very important that the car is in stock mode, in order to collect a complete fingerprint
+# - since some messages are published at low frequency, keep this script running for at least 30s,
+#   until all messages are received at least once
