+          The Mass Storage Gadget acts as a USB Mass Storage disk drive.
+          As its storage repository it can use a regular file or a block
+          device (in much the same way as the "loop" device driver),
+          specified as a module parameter or sysfs option.
+
+          This is heavily based on File-backed Storage Gadget and in most
+          cases you will want to use FSG instead.  This gadget is mostly
+          here to test the functionality of the Mass Storage Function
+          which may be used with composite framework.
+
+          Say "y" to link the driver statically, or "m" to build
+          a dynamically linked module called "g_file_storage".  If unsure,
+          consider File-backed Storage Gadget.
