+**NOTE:** NRI-plugins Helm installation has been successfully verified in both local clusters and major Cloud Providers' managed clusters, including:
+
+   -  AWS EKS
+        - kubernetes version: 1.28.x
+        - containerd version: 1.7
+        - node image: Amazon Linux 2, Ubuntu 20.04, 
+   - Google GKE
+        - kubernetes version: 1.28.x
+        - containerd version: 1.7
+        - node image: Container-Optimized OS from Google (COS), Ubuntu 22.04 
+   -  Azure AKS
+        - kubernetes version: 1.28.x
+        - containerd version: 1.7
+        - node image: Azure Linux Container Host, Ubuntu 20.04
+
+While Ubuntu 20.04/22.04 was used across all three CSP environments, it's worth noting that node images are not limited to Ubuntu 20.04/22.04 only. The majority of widely recognized Linux distributions should be suitable for use.
