 ## How to use
 
+### Prerequisite if validating against the K8s cluster
+
+kube-depre by default looks for `~/.kube/config` for kuberenetes configuration. If the configuration is stored in other file location, set that location in the `KUBECONFIG` environment variable.
+
+```bash
+export KUBECONFIG={config-location}
+```
+
