 Note that the operation performed by a batch will not be rolled back by terminating the batch. However, you can use reset to rollback your :workflow:workflows:.
 
-#### Restart, reset workflow
+#### Reset workflow
 The Reset command allows resetting a :workflow: to a particular point and continue running from there.
 There are a lot of use cases:
+
 - Rerun a failed :workflow: from the beginning with the same start parameters.
 - Rerun a failed :workflow: from the failing point without losing the achieved progress(history).
 - After deploying new code, reset an open :workflow: to let the :workflow: run to different flows.
 
+What this command allows you to do conceptually is to go back to an earlier point in the workflow's history and re-run from that point. It allows you to pick the beginning of the workflow's history, the most recent events (the end) or in (most) segements of the workflow's history. 
+
 You can reset to some predefined :event: types:
 ```bash
 cadence workflow reset -w <wid> -r <rid> --reset_type <reset_type> --reason "some_reason"
