 The `docker service logs` command batch-retrieves logs present at the time of execution.
 
+The `docker service logs` command can be used with either the name or ID of a
+service, or with the ID of a task. If a service is passed, it will display logs
+for all of the containers in that service. If a task is passed, it will only
+display logs from that particular task.
