 ### Expiring old revisions
 
+Using the `-r` or `--revisions` argument.
+
 All revisions that have been created before the specified age will be removed. If all revisions are expired, the note
 remains available, it just won't have any revisions to revert to. Once you continue editing it, new revisions will be
 added.
 
 ### Expiring old notes
 
+Using the `-n` or `--notes` argument.
+
 Notes that are being expired will be emailed to the account that initially created the note. This allows that user to
 restore the note, if necessary. Expiring a note will also remove all existing revisions for the note.
