 ### Additional information
 
-- [Draining nodes](/docs/tasks/administer-cluster/safely-drain-node/) before kubelet MINOR version
-  upgrades is required. In the case of control plane nodes, they could be running CoreDNS Pods or other critical workloads.
+- The instructions below outline when to drain each node during the upgrade process.
+If you are performing a **minor** version upgrade for any kubelet, you **must**
+first drain the node (or nodes) that you are upgrading. In the case of control plane nodes,
+they could be running CoreDNS Pods or other critical workloads. For more information see
+[Draining nodes](/docs/tasks/administer-cluster/safely-drain-node/).
 - All containers are restarted after upgrade, because the container spec hash value is changed.

 ### 附加信息
 
-- 在对 kubelet 作次版本升版时需要[腾空节点](/zh/docs/tasks/administer-cluster/safely-drain-node/)。
-  对于控制面节点，其上可能运行着 CoreDNS Pods 或者其它非常重要的负载。
+- 下述说明了在升级过程中何时腾空每个节点。如果你正在对任何 kubelet 进行小版本升级，
+  你需要先腾空待升级的节点（或多个节点）。对于控制面节点，其上可能运行着 CoreDNS Pods
+  或者其它非常重要的负载。更多信息见[腾空节点](/zh/docs/tasks/administer-cluster/safely-drain-node/)。
 - 升级后，因为容器规约的哈希值已更改，所有容器都会被重新启动。
 
+<!--
+- To verify that the kubelet service has successfully restarted after the kubelet has been upgraded,
+you can execute `systemctl status kubelet`  or view the service logs with `journalctl -xeu kubelet`.
+- Usage of the `--config` flag of `kubeadm upgrade` with
+[kubeadm configuration API types](/docs/reference/config-api/kubeadm-config.v1beta3)
+with the purpose of reconfiguring the cluster is not recommended and can have unexpected results. Follow the steps in
+[Reconfiguring a kubeadm cluster](/docs/tasks/administer-cluster/kubeadm/kubeadm-reconfigure) instead.
+-->
+
+- 要验证 kubelet 服务在升级后是否成功重启，可以执行 `systemctl status kubelet`
+  或 `journalctl -xeu kubelet` 查看服务日志。
+- 不建议使用 `kubeadm upgrade` 的 `--config 参数和 [kubeadm 配置 API 类型](/zh/docs/reference/config-api/kubeadm-config.v1beta3)
+  来重新配置集群，这样会产生意想不到的结果。请按照[重新配置 kubeadm 集群](/zh/docs/tasks/administer-cluster/kubeadm/kubeadm-reconfigure)
+  中的步骤来进行。
