+Display Only Missing Album Art
+------------------------------
+
+Use the ``fetchart`` command with the ``-m`` switch in order to display only missing
+art::
+
+    $ beet fetchart [-m] [query]
+
+By default the command will display all results, the ``-m`` or ``--missing``
+switch will only display results for those album arts that still miss.
