-Minimum in-sync replicas is the minimum number of replicas that must acknowledge a write for the write to be considered successful. This property assumes that the producer requests acknowledgments from all replicas (`acks` set to `all`). If this minimum is not met, the producer raises an exception (`NotEnoughReplicas` or `NotEnoughReplicasAfterAppend`).
+Minimum in-sync replicas is the minimum number of replicas that must acknowledge a write for the write to be considered successful. To enforce the minimum in-sync replicas value, (set `acks` to `all`) to ensure that producers request acknowledgements from all replicas. If this minimum is not met, the producer raises an exception (`NotEnoughReplicas` or `NotEnoughReplicasAfterAppend`).
