+5. **How do I use KRO resources with ArgoCD?**
+
+   To use KRO resources with ArgoCD, you need to add a specific tracking annotation
+   to all templated resources in your ResourceGraphDefinition. 
+   
+   The following code needs to be added to each templated resource:
+
+   ```yaml
+   metadata:
+      ownerReferences:
+         - apiVersion: kro.run/v1alpha1
+           kind: ${schema.kind}
+           name: ${schema.metadata.name}
+           uid: ${schema.metadata.uid}
+           blockOwnerDeletion: true
+           controller: false
+      annotations:
+        argocd.argoproj.io/tracking-id: ${schema.metadata.?annotations["argocd.argoproj.io/tracking-id"]}
+   ```
+
+   This annotation allows ArgoCD to properly track and manage the resources
+   created by KRO instances. 
+
+
+   ![ArgoCD RGD tracked Instance](../../static/img/KRO-ArgoCD-Tracking.png)
+   
+   Note that the example shown above depicts ArgoCD's default resource tracking 
+   via annotations. You may choose to use `annotation+label` or just `label` and 
+   if so the example has to be modified to support your configuration. 
+   For more detailed information about ArgoCD resource tracking, please see the
+   [ArgoCD documentation](https://argo-cd.readthedocs.io/en/stable/user-guide/resource_tracking/).
