 =head1 BUGS AND LIMITATIONS
 
-Unknown.
+B<efa-m> uses the VRR EFA service by default, which seems to contain the
+greatest available set of information. However, some cities (e.g. Berlin
+or parts of Hamburg) are incomplete. B<efa-m> is not yet able to choose the
+appropriate EFA URL for these by itself, it needs to be done manually with
+the B<-u>, B<--efa-url> option.
