 - If there is another patch to apply, then add a fuzzing tag so that the
   packets can easily be differentiated and appended to the official
-  "fuzzing_spa_packets" file:
+  "fuzzing_spa_packets" file.  Note that adding the --fuzzing-class argument
+  assumes that a patch has been applied to lib/fko_encode.c to manipulate SPA
+  packet data after the various user-supplied data has been provided (and this
+  data itself is valid - it is the encoding itself that the patch is supposed
+  to mess with).  If the --fuzzing-class arg is left off, then the user fields
+  are built using invalid data.
