-> This project is still in the early development stage which means it's not ready for production as APIs, commands, flags, etc. are subject to change, but also that your feedback can still help to shape it. Please try it out and let us know what you like, dislike, what works, what doesn't, etc.
-
 ## Why we are building it?
-Global hyper-scalers are leading the Managed Kubernetes space, while regional cloud providers, as well as large corporations, are struggling to offer the same level of experience to their developers because of the lack of the right tools. Also, Kubernetes solutions for the on-premises are designed with an enterprise-first approach and they are too costly when deployed at scale. Project Kamaji aims to solve this pain by leveraging multi-tenancy and simplifying how to run Kubernetes clusters at scale with a fraction of the operational burden.

+
+**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.
 
 ## How it works
-Kamaji turns any CNCF conformant Kubernetes cluster into an _“admin cluster”_ to orchestrate other Kubernetes clusters we're calling _“tenant clusters”_. As with every Kubernetes cluster, a tenant cluster has a set of nodes and a control plane, composed of several components: `APIs server`, `scheduler`, `controller manager`. What Kamaji does is deploy those components as a pod running in the admin cluster.
+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.

+![Architecture](docs/content/images/kamaji-dark.png#gh-dark-mode-only)
 
-And what about the tenant worker nodes? They are just worker nodes: regular instances, e.g. virtual or bare metal, connecting to the APIs server of the tenant cluster. Kamaji's goal is to manage the lifecycle of hundreds of these clusters, not only one, so how can we add another tenant cluster? As you could expect, Kamaji just deploys a new tenant control plane as a new pod in the admin cluster, and then it joins the new tenant worker nodes.
+## Getting started
 
-<p align="center">
-  <img src="assets/kamaji-light.png" />
-</p>
-
-All the tenant clusters built with Kamaji are fully compliant CNCF Kubernetes clusters and are compatible with the standard Kubernetes toolchains everybody knows and loves.
-
-<p align="center">

-</p>
-
-## Save the state
-Putting the tenant cluster control plane in a pod is the easiest part. Also, we have to make sure each tenant cluster saves the state to be able to store and retrieve data.
-
-A dedicated `etcd` cluster for each tenant cluster doesn’t scale well for a managed service because `etcd` data persistence can be cumbersome at scale, rising the operational effort to mitigate it. So we have to find an alternative keeping in mind our goal for a resilient and cost-optimized solution at the same time. As we can deploy any Kubernetes cluster with an external `etcd` cluster, we explored this option for the tenant control planes. On the admin cluster, we deploy a multi-tenant `etcd` cluster storing the state of multiple tenant clusters.
-
-With this solution, the resiliency is guaranteed by the usual `etcd` mechanism, and the pods' count remains under control, so it solves the main goal of resiliency and costs optimization. The trade-off here is that we have to operate an external `etcd` cluster and manage the access to be sure that each tenant cluster uses only its data. Also, there are limits in size in `etcd`, defaulted to 2GB and configurable to a maximum of 8GB. We’re solving this issue by pooling multiple `etcd` and sharding the tenant control planes.
-
-## Use cases
-Kamaji project has been initially started as a solution for actual and common problems such as minimizing the Total Cost of Ownership while running Kubernetes at scale. However, it can open a wider range of use cases. Here are a few:
-
-### Managed Kubernetes
-Enabling companies to provide Cloud Native Infrastructure with ease by introducing a strong separation of concerns between management and workloads. Centralize clusters management, monitoring, and observability by leaving developers to focus on the applications, increase productivity and reduce operational costs. 
-
-### Control Plane as a Service
-Provide Kubernetes control plane in a self-service fashion by running management and workloads on different infrastructures and cost centers with the option of Bring Your Own Device - BYOD.
-
-### Edge Computing
-Distribute Kubernetes workloads across edge computing locations without having to manage multiple clusters across various providers. Centralize management of hundreds of control planes while leaving workloads to run isolated on their own dedicated infrastructure.
-
-### Cluster Simulations
-Test a new Kubernetes API or experimental flag or a new tool without impacting production operations. Kamaji will let you simulate such things in a safe and controlled environment.
+Please refer to the [Getting Started guide](https://kamaji.clastix.io/getting-started/) to deploy a minimal setup of Kamaji on KinD.
 
 ## Features
 
-### 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 client does not see differences between a Kamaji provisioned cluster and a dedicated cluster.

-## FAQ
-Q. What does Kamaji means?
-
-A. Kamaji is named as the character _Kamaji_ from the Japanese movie [_Spirited Away_](https://en.wikipedia.org/wiki/Spirited_Away).
-
-Q. Is Kamaji another Kubernetes distribution?
-
-A. No, Kamaji is a tool you can install on top of any CNCF conformant Kubernetes to provide hundreds of managed Tenant clusters as a service. We tested Kamaji on vanilla Kubernetes 1.23+, KinD, and MS Azure AKS. We expect it to work smoothly on other Kubernetes distributions. The tenant clusters made with Kamaji are conformant CNCF Kubernetes vanilla clusters built with `kubeadm`.
-
-Q. Is it safe to run Kubernetes control plane components in a pod?
-
-A. Yes, the tenant control plane components are packaged in the same way they are running in bare metal or virtual nodes. We leverage the `kubeadm` code to set up the control plane components as they were running on a server. The same unchanged images of upstream `APIs server`, `scheduler`, `controller manager` are used.
-
-Q. And what about multi-tenant `etcd`? I never heard of it.
-
-A. Even if multi-tenant deployment for `etcd` is not a common practice, multi-tenancy, RBAC, and client authentication has been [supported](https://etcd.io/docs/v3.5/op-guide/authentication/) in `etcd` from a long time. 
-
-Q. You already provide a Kubernetes multi-tenancy solution with [Capsule](capsule.clastix.io). Why does Kamaji matter?
-
-A. Lighter Multi-Tenancy solutions, like Capsule shares the Kubernetes control plane among all tenants keeping tenant namespaces isolated by policies. While these solutions are the right choice by balancing between features and ease of usage, there are cases where a tenant user requires access to the control plane, for example, when a tenant requires to manage CRDs on his own. With Kamaji, you can provide admin permissions to the tenants.
-
-Q. So I need a costly cloud infrastructure to try Kamaji?
-
-A. No, it is possible to try Kamaji on your laptop with [KinD](./deploy/kind/README.md).

+
+## Requirements
+
+Kubernetes: `>=1.21.0-0`
+
+[Kamaji](https://github.com/clastix/kamaji) requires a [multi-tenant `etcd`](https://github.com/clastix/kamaji-internal/blob/master/deploy/getting-started-with-kamaji.md#setup-internal-multi-tenant-etcd) cluster.
+This Helm Chart starting from v0.1.1 provides the installation of an internal `etcd` in order to streamline the local test. If you'd like to use an externally managed etcd instance, you can specify the overrides and by setting the value `etcd.deploy=false`.
+
+> For production use an externally managed `etcd` is highly recommended, the `etcd` addon offered by this Chart is not considered production-grade.
+
+## Install Kamaji
+
+To install the Chart with the release name `kamaji`:
+
+        helm upgrade --install --namespace kamaji-system --create-namespace clastix/kamaji
+
+Show the status:
+
+        helm status kamaji -n kamaji-system
+
+Upgrade the Chart
+
+        helm upgrade kamaji -n kamaji-system clastix/kamaji
+
+Uninstall the Chart
+
+        helm uninstall kamaji -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 --install --namespace kamaji-system --create-namespace clastix/kamaji --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 --install --namespace kamaji-system --create-namespace clastix/kamaji --set etcd.deploy=false
+
+Here the values you can override:

+## Installing and managing etcd as DataStore
+
+Kamaji supports multiple data store, although `etcd` is the default one: thus, an initial cluster will be created upon the Chart installation.
+
+The `DataStore` resource can be configured with the proper values in case of overrides when using a different driver, otherwise all the required data will be inherited by the Chart values.

+
+[Kamaji](https://github.com/clastix/kamaji) requires a [multi-tenant `etcd`](https://github.com/clastix/kamaji-internal/blob/master/deploy/getting-started-with-kamaji.md#setup-internal-multi-tenant-etcd) cluster.
+This Helm Chart starting from v0.1.1 provides the installation of an internal `etcd` in order to streamline the local test. If you'd like to use an externally managed etcd instance, you can specify the overrides and by setting the value `etcd.deploy=false`.
+
+> For production use an externally managed `etcd` is highly recommended, the `etcd` addon offered by this Chart is not considered production-grade.
+
+## Install Kamaji
+
+To install the Chart with the release name `kamaji`:
+
+
+        helm upgrade --install --namespace kamaji-system --create-namespace clastix/kamaji
+
+Show the status:
+
+        helm status kamaji -n kamaji-system
+
+Upgrade the Chart
+
+        helm upgrade kamaji -n kamaji-system clastix/kamaji
+
+Uninstall the Chart
+
+        helm uninstall kamaji -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 --install --namespace kamaji-system --create-namespace clastix/kamaji --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 --install --namespace kamaji-system --create-namespace clastix/kamaji --set etcd.deploy=false
+
+Here the values you can override:
+
+{{ template "chart.valuesSection" . }}
