+# Istio CNI Helm Chart
+
+This chart installs the Istio CNI Plugin. See the [CNI installation guide](https://istio.io/latest/docs/setup/additional-setup/cni/)
+for more information.
+
+## Setup Repo Info
+
+```console
+helm repo add istio https://istio-release.storage.googleapis.com/charts
+helm repo update
+```
+
+_See [helm repo](https://helm.sh/docs/helm/helm_repo/) for command documentation._
+
+## Installing the Chart
+
+To install the chart with the release name `istio-cni`:
+
+```console
+helm install istio-cni istio/cni -n kube-system
+```
+
+Installation in `kube-system` is recommended to ensure the [`system-node-critical`](https://kubernetes.io/docs/tasks/administer-cluster/guaranteed-scheduling-critical-addon-pods/)
+`priorityClassName` can be used. You can install in other namespace only on K8S clusters that allow
+'system-node-critical' outside of kube-system.
+
+## Configuration
+
+To view support configuration options and documentation, run:
+
+```console
+helm show values istio/istio-cni
+```
+
+### Profiles
+
+Istio Helm charts have a concept of a `profile`, which is a bundled collection of value presets.
+These can be set with `--set profile=<profile>`.
+For example, the `demo` profile offers a preset configuration to try out Istio in a test environment, with additional features enabled and lowered resource requirements.
+
+For consistency, the same profiles are used across each chart, even if they do not impact a given chart.
+
+Explicitly set values have highest priority, then profile settings, then chart defaults.
+
+As an implementation detail of profiles, the default values for the chart are all nested under `defaults`.
+When configuring the chart, you should not include this.
+That is, `--set some.field=true` should be passed, not `--set defaults.some.field=true`.
+
+### Ambient
+
+To enable ambient, you can use the ambient profile: `--set profile=ambient`.
+
+#### Calico
+
+For Calico, you must also modify the settings to allow source spoofing:
+
+- if deployed by operator,  `kubectl patch felixconfigurations default --type='json' -p='[{"op": "add", "path": "/spec/workloadSourceSpoofing", "value": "Any"}]'`
+- if deployed by manifest, add env `FELIX_WORKLOADSOURCESPOOFING` with value `Any` in `spec.template.spec.containers.env` for daemonset `calico-node`. (This will allow PODs with specified annotation to skip the rpf check. )
+
+### GKE notes
+
+On GKE, 'kube-system' is required.
+
+If using `helm template`, `--set cni.cniBinDir=/home/kubernetes/bin` is required - with `helm install`
+it is auto-detected.
