 To deploy the EndpointPicker in a high-availability (HA) active-passive configuration, you can enable leader election. When enabled, the EPP deployment will have multiple replicas, but only one "leader" replica will be active and ready to process traffic at any given time. If the leader pod fails, another pod will be elected as the new leader, ensuring service continuity.
 
-To enable HA, set `inferenceExtension.enableLeaderElection` to `true` and increase the number of replicas in your `values.yaml` file:
