+1. The next step is to establish connection from the local client to the cloud instance. Login to the Oracle Cloud Console and create a new `API key` from the user profile.
+Follow the steps here: https://docs.oracle.com/en-us/iaas/Content/API/Concepts/apisigningkey.htm#two
+Download a Private Key and Add a new API key as mentioned in the doc. Copy the config file to `~/.oci/config` and update the path to the private key file in config.
+With this the config is ready for usage by the CLI.
 
-```bash

-ACCOUNT=release-right-meow
-
-# Connected to the `prow` in the `tekton-releases` GCP project
-GCP_ACCOUNT="$ACCOUNT@tekton-releases.iam.gserviceaccount.com"
+1. Test the connection by doing a get of the OKE cluster id.
+Refer here https://docs.oracle.com/en-us/iaas/tools/oci-cli/3.70.0/oci_cli_docs/cmdref/ce.html for the CLI options.
+Command to create a kubeconfig in your local could be obtained from console navigating to the OKE > Actions > Access Cluster. Run the command pointing to the PUBLIC_ENDPOINT and we should be connected to the cluster.
 
-# 1. Create a private key for the service account
-gcloud iam service-accounts keys create $KEY_FILE --iam-account $GCP_ACCOUNT
+1. [Setup a context to connect to the dogfooding cluster](./release-cheat-sheet.md#setup-dogfooding-context) 
 
-# 2. Create kubernetes secret, which we will use via a service account and directly mounting
-kubectl create secret generic $GENERIC_SECRET --from-file=./$KEY_FILE
-
-# 3. Add the docker secret to the service account
-kubectl apply -f tekton/account.yaml
-kubectl patch serviceaccount $ACCOUNT \
-  -p "{\"secrets\": [{\"name\": \"$GENERIC_SECRET\"}]}"
+1. When executing release pipelines, some tasks require `oci cli` commands. The CLI requires credentials which should be created as a Kubernetes secret and mounted to the respective task's workspace. For example refer the precheck definition.
