 After you have the above prerequsites completed, you can proceed to the next section for your environment to provision the Oracle Database Sharding Topology.
 
 ## Provisioning Sharding Topology in a Cloud-Based Kubernetes Cluster (OKE in this case)
 
 Deploy Oracle Database sharding topology on your Cloud based Kubernetes cluster. In this example, the deployment uses the YAML file based on `OCI OKE` cluster. There are multiple use case possible for deploying the Oracle Database sharding topology.

 ## Connecting to Shard Databases
 
-After the Oracle Database Sharding Topology has been provisioned using the Sharding Controller in Oracle Database Kubernetes Operator, you can follow the steps in this document to connect to the Sharded Database or to the individual Shards: [Database Connectivity](./doc/sharding/provisioning/database_connection.md)
