+The `targets:` in the `GitRepo` resource select clusters to deploy on. The `targetCustomizations:` in `fleet.yaml` override Helm values only and do not change targeting.

 To demonstrate how to deploy Kubernetes manifests across different clusters with customization using Fleet, we will use [multi-cluster/helm/fleet.yaml](https://github.com/rancher/fleet-examples/blob/master/multi-cluster/helm/fleet.yaml).
 
 **Situation:** User has three clusters with three different labels: `env=dev`, `env=test`, and `env=prod`. User wants to deploy a frontend application with a backend database across these clusters.
