 DESCRIPTION
 
-    Time Machine Importer modifies the metadata of a backup drive to match the 
-    current computer's model and unique identifiers (primary MAC address and
-    hardware platform UUID/provisioning UDID) and attempts to 'inherit' the
-    backup history.
+    Time Machine Importer attempts to inherit the backup history of a backup
+    drive. If the backup drive is not paired to the current computer, Time
+    Machine Importer will attempt to pair the drive with the current computer
+    by modifying the model, MAC address, and UUID/UDID reflected in the
+    metadata of the backup drive.
 
     The backup drive should be specified by disk or volume name (or path) or
-    the mount point of the backup drive. If Time Machine Importer cannot find
-    an appropriate disk volume or mount point, it will check to see if the 
-    specified directory is a valid Backups.backupdb location (or a machine
-    directory under one).
-
-    A future version may attempt to detect HFS+ or APFS partitions serving as
-    backup drives, and, if a backup drive is specified as a device path, it
-    will automagically choose the correct backup path.
+    the mount point of the backup drive. For example:
+        - ${0} /dev/disk1s1
+        - ${0} /Volumes/TMBACKUP
 
+    While some additional heuristics may assist in identifying a backup drive
+    that is specified in other ways, they are untested and not guaranteed
+    to work correctly.
