 Begins an interactive review session, where you can mark tasks as reviewed,

-Finds your pending and waiting tasks that need to be reviewed. By default this
-means any task with a missing 'reviewed' date, or with a 'reviewed' date that
-is older than a week. This means if you run the 'review' command to completion,

+You can terminate a review session at any time, and the next review session

+
+To find tasks needing review, the '_reviewed' custom report is created and run,
+which filters tasks that have a missing 'reviewed' UDA date, or have not been
+reviewed for a week.
+
+This means that if you run a review session to completion, there will be no
+need to review again for a week, and the review command will simply do nothing
+until then.
+
+The one week review cycle is defined by the '_reviewed' custom report, which
+can be modified if you prefer a monthly review cycle.

 If 'N' is provided, the session is limited to reviewing only N tasks.
