 ### Google Drive Listener
 
+*Note that the Google Drive listener currently has a pre-filter maximum of 1000
+files. That means that having more files than this in an account is not (yet)
+supported; such files might be ignored entirely, or strange behaviour might be
+encountered depending on the order in which the files are returned.*
