+# CNI METRICS HELPER
+
+This chart provides a Kubernetes deployment for the Amazon VPC CNI Metrics Helper, which is used to collect metrics for the Amazon VPC CNI plugin for Kubernetes.
+
+## Prerequisites
+
+- Kubernetes 1.11+ running on AWS
+- Helm 3.0+
+
+## Installing the Chart
+
+First add the EKS repository to Helm:
+
+```shell
+helm repo add eks https://aws.github.io/eks-charts
+```
+
+To install the chart with the release name `cni-metrics-helper` and default configuration:
+
+```shell
+$ helm install cni-metrics-helper --namespace kube-system eks/cni-metrics-helper
+```
+
+To install manually, clone the Amazon VPC CNI for Kubernetes repository to your local machine:
+
+```shell
+$ git clone https://github.com/aws/amazon-vpc-cni-k8s.git
+```
+
+Use the helm install command to install the chart into your Kubernetes cluster:
+
+```shell
+$ helm install cni-metrics-helper --namespace kube-system ./charts/cni-metrics-helper
+```
+
+To uninstall:
+
+```shell
+$ helm uninstall cni-metrics-helper --namespace kube-system
+```
+
+## Configuration
+
+The following table lists the configurable parameters for this chart and their default values.
+
+| Parameter                    | Description                                                   | Default            |
+|------------------------------|---------------------------------------------------------------|--------------------|
+| fullnameOverride             | Override the fullname of the chart                            | cni-metrics-helper |
+| image.region                 | ECR repository region to use. Should match your cluster       | us-west-2          |
+| image.tag                    | Image tag                                                     | v1.12.2            |
+| image.account                | ECR repository account number                                 | 602401143452       |
+| image.domain                 | ECR repository domain                                         | amazonaws.com      |
+| env.USE_CLOUDWATCH           | Whether to export CNI metrics to CloudWatch                   | true               |
+| env.AWS_CLUSTER_ID           | ID of the cluster to use when exporting metrics to CloudWatch | default            |
+| env.AWS_VPC_K8S_CNI_LOGLEVEL | Log verbosity level (ie. FATAL, ERROR, WARN, INFO, DEBUG)     | INFO               |
+| serviceAccount.name          | The name of the ServiceAccount to use                         | nil                |
+| serviceAccount.create        | Specifies whether a ServiceAccount should be created          | true               |
+| serviceAccount.annotations   | Specifies the annotations for ServiceAccount                  | {}                 |
+
+Specify each parameter using the `--set key=value[,key=value]` argument to `helm install` or provide a YAML file containing the values for the above parameters:
+
+```shell
+$ helm install cni-metrics-handler --namespace kube-system eks/cni-metrics-handler --values values.yaml
+```
+
+Manual install:
+```shell
+$ helm install cni-metrics-helper --namespace kube-system ./charts/cni-metrics-helper --values values.yaml
+```
+
+## Resources
+
+| Parameter                 | Description                                    | Default |

+
+For example, to set a CPU limit of 200m and a memory limit of 256Mi for the cni-metrics-helper pods, you can use the following command:
+
+```shell
+$ helm install cni-metrics-helper ./charts/cni-metrics-helper --namespace kube-system --set resources.limits.cpu=200m,resources.limits.memory=256Mi
