+Unimported Plugin
+=================
+
+The ``unimported`` plugin allows to list all files in the library folder which are not listed in the beets library database, including art files.
+
+Command Line Usage
+------------------
+
+To use the ``unimported`` plugin, enable it in your configuration (see
+:ref:`using-plugins`). Then use it by invoking the ``beet unimported`` command.
+The command will list all files in the library folder which are not imported. You can
+exclude file extensions using the configuration file::
+
+    unimported:
+        ignore_extensions: jpg png
+
+The default configuration list all unimported files, ignoring no extensions.
