-        First install TiDB Operator in a Kubernetes cluster according to [Deploy TiDB Operator in Kubernetes](deploy-tidb-operator.md), then deploy your TiDB clusters according to [Deploy TiDB in General Kubernetes](deploy-on-general-kubernetes.md).
+<NavColumn>
+<ColumnTitle>Deploy TiDB</ColumnTitle>
 
-        You also need to adjust the configuration of the Kubernetes cluster based on [Prerequisites for TiDB in Kubernetes](prerequisites.md) and configure the local PV for your Kubernetes cluster to achieve low latency of local storage for TiKV according to [Local PV Configuration](configure-storage-class.md#local-pv-configuration).

-Before deploying TiDB on any of the above two environments, you can always refer to [TiDB Cluster Configuration Document](configure-a-tidb-cluster.md) to customize TiDB configurations.

-After the deployment is complete, see the following documents to use, operate, and maintain TiDB clusters in Kubernetes:

-TiDB in Kubernetes provides a dedicated command-line tool `tkctl` for cluster management and auxiliary diagnostics. Meanwhile, some of TiDB's tools are used differently in Kubernetes. You can:
+- [Upgrade a TiDB Cluster](upgrade-a-tidb-cluster.md)
+- [Upgrade TiDB Operator](upgrade-tidb-operator.md)
+- [Scale a TiDB Cluster](scale-a-tidb-cluster.md)
+- [Backup and Restore](backup-and-restore-using-helm-charts.md)
+- [Maintain Kubernetes Nodes](maintain-a-kubernetes-node.md)
+- [Use Automatic Failover](use-auto-failover.md)
 
-+ Use `tkctl` according to [`tkctl` Guide](use-tkctl.md );
-+ See [Tools in Kubernetes](tidb-toolkit.md) to understand how TiDB tools are used in Kubernetes.
+</NavColumn>
 
-Finally, when a new version of TiDB Operator is released, you can refer to [Upgrade TiDB Operator](upgrade-tidb-operator.md) to upgrade to the latest version.
