+.. note: When adding a path to snap-schedule, remember to strip off the mount
+   point path prefix. Paths to snap-schedule should start at the appropriate
+   CephFS file system root and not at the host file system root.
+   e.g. if the Ceph File System is mounted at ``/mnt`` and the path under which
+   snapshots need to be taken is ``/mnt/some/path`` then the acutal path required
+   by snap-schedule is only ``/some/path``.
+
+.. note: It should be noted that the "created" field in the snap-schedule status
+   command output is the timestamp at which the schedule was created. The "created"
+   timestamp has nothing to do with the creation of actual snapshots. The actual
+   snapshot creation is accounted for in the "created_count" field, which is a
+   cumulative count of the total number of snapshots created so far.

 Active and inactive schedules
 -----------------------------
 Snapshot schedules can be added for a path that doesn't exist yet in the
