 - **Managing core addons**: Kamaji allows configuring automatically `kube-proxy`, `CoreDNS`, and `konnectivity`, with automatic remediation in case of user errors (e.g.: deleting the `CoreDNS` deployment).
 - **Auto Healing**: the `TenantControlPlane` objects in the management cluster are tracked by Kamaji, in case of deletion of those, everything is created in an idempotent way.
 - **Datastore multi-tenancy**: optionally, Kamaji allows running multiple Control Planes on the same _Datastore_ instance leveraging on the multi-tenancy of each driver, decreasing operations and optimizing costs.

+## Source Code
+
+* <https://github.com/clastix/kamaji>
+
+[Kamaji](https://github.com/clastix/kamaji) Custom Resource Definitions packaged as Helm Charts.
+
+## How to use this chart
+
+Add `clastix` Helm repository:
+
+    helm repo add clastix https://clastix.github.io/charts
+
+Install the Chart with the release name `kamaji-crds`:
+
+    helm upgrade --install --namespace kamaji-system --create-namespace kamaji-crds clastix/kamaji-crds
+
+Show the status:
+
+    helm status kamaji-crds -n kamaji-system
+
+Upgrade the Chart
+
+    helm upgrade kamaji-crds -n kamaji-system clastix/kamaji-crds
+
+Uninstall the Chart
+
+    helm uninstall kamaji-crds -n kamaji-system
+
+## Customize the installation
+
+There are two methods for specifying overrides of values during Chart installation: `--values` and `--set`.
+
+The `--values` option is the preferred method because it allows you to keep your overrides in a YAML file, rather than specifying them all on the command line. Create a copy of the YAML file `values.yaml` and add your overrides to it.
+
+Specify your overrides file when you install the Chart:
+
+    helm upgrade kamaji-crds --install --namespace kamaji-system --create-namespace clastix/kamaji-crds --values myvalues.yaml
+
+The values in your overrides file `myvalues.yaml` will override their counterparts in the Chart's values.yaml file. Any values in `values.yaml` that weren’t overridden will keep their defaults.
+
+If you only need to make minor customizations, you can specify them on the command line by using the `--set` option. For example:
+
+    helm upgrade kamaji-crds --install --namespace kamaji-system --create-namespace clastix/kamaji-crds --set kamajiCertificateName=kamaji
+
+## Values
+
+| Key | Type | Default | Description |
+|-----|------|---------|-------------|
+| fullnameOverride | string | `""` | Overrides the full name of the resources created by the chart. |
+| kamajiCertificateName | string | `"kamaji-serving-cert"` | The cert-manager Certificate resource name, holding the Certificate Authority for webhooks. |
+| kamajiNamespace | string | `"kamaji-system"` | The namespace where Kamaji has been installed: required to inject the Certificate Authority for cert-manager. |
+| kamajiService | string | `"kamaji-webhook-service"` | The Kamaji webhook Service name. |
+| nameOverride | string | `""` | Overrides the name of the chart for resource naming purposes. |
