+# This script provides a way to update the targetRevision of an ArgoCD application in all SMPC stage clusters.
+# The script will loop through each cluster, port-forward ArgoCD server, authenticate to it, update the targetRevision of the application, and close port-forward.
+#
+# Usage: ./argo_stage_update_revision.sh <your-branch | main>
+#
+# Pre-requisites:
+# 1. Ensure that you have the ArgoCD CLI installed on your local machine. (brew install argocd)
+# 2. Ensure that you have the kubectl and kubectx installed on your local machine.
+# 3. Ensure that your kubeconfig is configured to access the target clusters.
+
+
+# Define clusters and ArgoCD application details
