+### 🤔 What is Kamaji?
 
-## Why we are building it?
-Global hyper-scalers are leading the Managed Kubernetes space, while other cloud providers, as well as large corporations, are struggling to offer the same experience to their DevOps teams because of the lack of the right tools. Also, current Kubernetes solutions are mainly designed with an enterprise-first approach and they are too costly when deployed at scale.
+**Kamaji** is the **Kubernetes Control Plane Manager** leveraging on the concept of [**Hosted Control Plane**](https://clastix.io/post/the-raise-of-hosted-control-plane-in-kubernetes/).
 
-**Kamaji** aims to solve these pains by leveraging multi-tenancy and simplifying how to run multiple control planes on the same infrastructure with a fraction of the operational burden.
+Kamaji's approach is based on running the Kubernetes Control Plane components in Pods instead of dedicated machines.
+This allows operating Kubernetes clusters at scale, with a fraction of the operational burden.
+Thanks to this approach, running multiple Control Planes can be cheaper and easier to deploy and operate.
 
-## How it works
-Kamaji turns any Kubernetes cluster into an _“admin cluster”_ to orchestrate other Kubernetes clusters called _“tenant clusters”_. Kamaji is special because the Control Planes of _“tenant clusters”_ are just regular pods instead of dedicated Virtual Machines. This solution makes running Control Planes at scale cheaper and easier to deploy and operate.
+_Kamaji is like a fleet of Site Reliability Engineers with expertise codified into its logic, working 24/7 to keep up and running your Control Planes._

-## Getting started
+### 📖 How it works
 
-Please refer to the [Getting Started guide](https://kamaji.clastix.io/getting-started/) to deploy a minimal setup of Kamaji on KinD.
+Kamaji is extending the Kubernetes API capabilities thanks to [Custom Resource Definitions](https://kubernetes.io/docs/concepts/extend-kubernetes/api-extension/custom-resources/#customresourcedefinitions).
 
-## Features
+By installing Kamaji, two pairs of new APIs will be available:
 
-- **Self Service Kubernetes:** leave users the freedom to self-provision their Kubernetes clusters according to the assigned boundaries.
-- **Multi-cluster Management:** centrally manage multiple tenant clusters from a single admin cluster. Happy SREs. 
-- **Cheaper Control Planes:** place multiple tenant control planes on a single node, instead of having three nodes for a single control plane.
-- **Stronger Multi-Tenancy:** leave tenants to access the control plane with admin permissions while keeping the tenant isolated at the infrastructure level.
-- **Kubernetes Inception:** use Kubernetes to manage Kubernetes by re-using all the Kubernetes goodies you already know and love.
-- **Full APIs compliant:** tenant clusters are fully CNCF compliant built with upstream Kubernetes binaries. A user does not see differences between a Kamaji provisioned cluster and a dedicated cluster.
+- `TenantControlPlane`, the instance definition of your desired Kubernetes Control Plane
+- `Datastore`, the backing store used by one (or more) `TenantControlPlane`
 
-## Roadmap
+The `TenantControlPlane` (short-named as `tcp`) objects are Namespace-scoped and allows configuring every aspect of your desired Control Plane.
+Besides the Kubernetes configuration values, you can specify the Pod options such as limit, request, tolerations, node selector, etc.,
+as well as how these should be exposed (e.g.: using a `ClusterIP`, a `LoadBalancer`, or a `NodePort`).
 
-- [x] Benchmarking
-- [ ] Stress-test
-- [x] Support for dynamic address allocation on native Load Balancer
+The `TenantControlPlane` is the stateless definition of the Control Plane allowing to set up the required components for a full-fledged Kubernetest cluster.
+The state is managed by the `Datastore` API, a cluster-scoped resource which can hold the data of one or more Kubernetes clusters.
+
+> For further information about the API specifications and all the available options,
+> refer to the official [API reference](https://kamaji.clastix.io/reference/api/#tenantcontrolplane).
+
+### ⭐️ Main features
+
+- **Fast provisioning time**: depending on the infrastructure, Tenant Control Planes are up and ready to serve traffic in **16 seconds**.
+- **Streamlined update**: the rollout to a new Kubernetes version for a given Tenant Control Plane takes just **10 seconds**, with a Blue/Green deployment to avoid serving mixed Kubernetes versions.
+- **Resource optimization**: thanks to the Datastore decoupling, there's no need of odd number instances (e.g.: RAFT consensus) by allowing to save up to 60% of HW resources.
+- **Scale from zero to the moon**: scale down the instance when there's no usage, or automatically scale to support the traffic spikes reusing the Kubernetes patterns.
+- **Declarative approach, constant reconciliation**: thanks to the Operator pattern, drift detection happens in real-time, maintaining the desired state.
+- **Automated certificates management**: Kamaji leverages on `kubeadm` and the certificates are automatically created and rotated for you.
+- **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.
+- **Overcoming `etcd` limitations**: optionally, Kamaji allows using a different _Datastore_ thanks to [`kine`](https://github.com/k3s-io/kine) by supporting `MySQL`, `PostgreSQL`, or `NATS` as an alternative.
+- **Simplifying mixed-networks setup**: thanks to [`Konnectivity`](https://kubernetes.io/docs/tasks/extend-kubernetes/setup-konnectivity/),
+  the Tenant Control Plane is connected to the worker nodes hosted in a different network, overcoming the no-NAT availability when dealing with nodes with a non routable IP address
+  (e.g.: worker nodes in a different infrastructure).
+
+### 🚀 Use cases
+
+- [**Creating a private Managed Kubernetes Service**](https://clastix.io/post/netsons-builds-a-managed-kubernetes-service-with-kamaji-and-open-stack/)
+- [**Building a Platform as a Service**](https://aenix.io/cozystack/)
+- [**Overcoming public Managed Kubernetes Services**](https://clastix.io/post/overcoming-eks-limitations-with-kamaji-on-aws/) such as EKS
+- [**Hybrid infrastructures**](https://clastix.io/post/bridging-the-gap-hybrid-kubernetes-clusters-with-remote-control-planes/):
+  host the Control Plane on the Cloud and worker nodes on prem or vice-versa, according to your needs.
+- [**Kubernetes at the edge**](https://clastix.io/post/edgevolution-unleashing-the-power-of-kubernetes-clusters-for-a-revolutionary-edge-computing-experience/):
+  take full advantage of the _Kubernetes API Server as a service_ paradigm.
+- **Kubernetes Control Plane as a Service:** centrally manage multiple Kubernetes clusters from a single management point (_Multi-Cluster management_). 
+- **High-density Control Plane:** place multiple control planes on the same infrastructure, instead of having dedicated machines for each control plane.
+- **Strong Multi-tenancy:** leave users to access the control plane with admin permissions while keeping them isolated at the infrastructure level.
+- **Kubernetes Inception:** use Kubernetes to manage Kubernetes with automation, high-availability, fault tolerance, and autoscaling out of the box. 
+- **Bring Your Own Device:** keep the control plane isolated from data plane. Worker nodes can join and run consistently from everywhere: cloud, edge, and data-center.
+- **Full CNCF compliant:** all clusters are built with upstream Kubernetes binaries, resulting in full CNCF compliant Kubernetes clusters.

+
+### 🐢 Cluster API support
+
+Kamaji is **not** a [Cluster API](https://cluster-api.sigs.k8s.io/) replacement, rather, it plays very well with it.
+
+Since Kamaji is just focusing on the Control Plane a [Kamaji's Cluster API Control Plane provider](https://github.com/clastix/cluster-api-control-plane-provider-kamaji) has been developed.

+* <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. |
