+# Kubernetes multi-tenancy made easy
+
+**Capsule** implements a multi-tenant and policy-based environment in your Kubernetes cluster. It is designed as a micro-services-based ecosystem with the minimalist approach, leveraging only on upstream Kubernetes.
 
 # What's the problem with the current status?
-Kubernetes introduces the _Namespace_ object type to create logical partitions of the cluster as isolated *slices*. However, implementing advanced multi-tenancy scenarios, it becomes soon complicated because of the flat structure of Kubernetes namespaces and the impossibility to share resources among namespaces belonging to the same tenant. To overcome this, cluster admins tend to provision a dedicated cluster for each groups of users, teams, or departments. As an organization grows, the number of clusters to manage and keep aligned becomes an operational nightmare, described as the well know phenomena of the _clusters sprawl_.
 
-# Entering Caspule
-Capsule takes a different approach. In a single cluster, the Capsule Controller aggregates multiple namespaces in a lightweight abstraction called _Tenant_. Within each tenant, users are free to create their namespaces and share all the assigned resources while the Capsule Policy Engine keeps the different tenants isolated from each other.

As an organization grows, the number of clusters to manage and keep aligned becomes an operational nightmare, described as the well known phenomena of the _clusters sprawl_.
 
-The _Network and Security Policies_, _Resource Quota_, _Limit Ranges_, _RBAC_, and other policies defined at the tenant level are automatically inherited by all the namespaces in the tenant. And users are free to operate their tenants in authonomy, without the intervention of the cluster administrator. Take a look at following diagram:

+Capsule takes a different approach. In a single cluster, the Capsule Controller aggregates multiple namespaces in a lightweight abstraction called _Tenant_, basically a grouping of Kubernetes Namespaces. Within each tenant, users are free to create their namespaces and share all the assigned resources. 
+
+On the other side, the Capsule Policy Engine keeps the different tenants isolated from each other. _Network and Security Policies_, _Resource Quota_, _Limit Ranges_, _RBAC_, and other policies defined at the tenant level are automatically inherited by all the namespaces in the tenant. Then users are free to operate their tenants in autonomy, without the intervention of the cluster administrator.

-# Common use cases for Capsule
-Please, refer to the corresponding [section](./docs/operator/use-cases/overview.md) in the project documentation for a detailed list of common use cases that Capsule can address.
-
-# Installation
-Make sure you have access to a Kubernetes cluster as administrator.
-
-There are two ways to install Capsule:
-
-* Use the Helm Chart available [here](./charts/capsule/README.md)
-* Use [`kustomize`](https://github.com/kubernetes-sigs/kustomize)
-
-## Install with kustomize
-Ensure you have `kubectl` and `kustomize` installed in your `PATH`. 
-
-Clone this repository and move to the repo folder:
-
-```
-$ git clone https://github.com/clastix/capsule
-$ cd capsule
-$ make deploy
-```
-
-It will install the Capsule controller in a dedicated namespace `capsule-system`.
-
-## How to create Tenants
-Use the scaffold [Tenant](config/samples/capsule_v1alpha1_tenant.yaml) and simply apply as cluster admin.
-
-```
-$ kubectl apply -f config/samples/capsule_v1alpha1_tenant.yaml
-tenant.capsule.clastix.io/oil created
-```
-
-You can check the tenant just created as
-
-```
-$ kubectl get tenants
-NAME      NAMESPACE QUOTA   NAMESPACE COUNT   OWNER NAME   OWNER KIND   NODE SELECTOR    AGE
-oil       3                 0                 alice        User                          1m
-```
-
-## Tenant owners
-Each tenant comes with a delegated user or group of users acting as the tenant admin. In the Capsule jargon, this is called the _Tenant Owner_. Other users can operate inside a tenant with different levels of permissions and authorizations assigned directly by the Tenant Owner.
-
-Capsule does not care about the authentication strategy used in the cluster and all the Kubernetes methods of [authentication](https://kubernetes.io/docs/reference/access-authn-authz/authentication/) are supported. The only requirement to use Capsule is to assign tenant users to the the group defined by `--capsule-user-group` option, which defaults to `capsule.clastix.io`.
-
-Assignment to a group depends on the authentication strategy in your cluster.
-
-For example, if you are using `capsule.clastix.io`, users authenticated through a _X.509_ certificate must have `capsule.clastix.io` as _Organization_: `-subj "/CN=${USER}/O=capsule.clastix.io"`
-
-Users authenticated through an _OIDC token_ must have
-
-```json
-...
-"users_groups": [
-    "capsule.clastix.io",
-    "other_group"
-]
-```
-
-in their token.
-
-The [hack/create-user.sh](hack/create-user.sh) can help you set up a dummy `kubeconfig` for the `alice` user acting as owner of a tenant called `oil`
-
-```bash
-./hack/create-user.sh alice oil
-creating certs in TMPDIR /tmp/tmp.4CLgpuime3 
-Generating RSA private key, 2048 bit long modulus (2 primes)
-............+++++
-........................+++++
-e is 65537 (0x010001)
-certificatesigningrequest.certificates.k8s.io/alice-oil created
-certificatesigningrequest.certificates.k8s.io/alice-oil approved
-kubeconfig file is: alice-oil.kubeconfig
-to use it as alice export KUBECONFIG=alice-oil.kubeconfig
-```
-
-## Working with Tenants
-Log in to the Kubernetes cluster as `alice` tenant owner
-
-```
-$ export KUBECONFIG=alice-oil.kubeconfig
-```
-
-and create a couple of new namespaces
-
-```
-$ kubectl create namespace oil-production
-$ kubectl create namespace oil-development
-```
-
-As user `alice` you can operate with fully admin permissions:
-
-```
-$ kubectl -n oil-development run nginx --image=docker.io/nginx 
-$ kubectl -n oil-development get pods
-```
-
-but limited to only your own namespaces:
-
-```
-$ kubectl -n kube-system get pods
-Error from server (Forbidden): pods is forbidden:
-User "alice" cannot list resource "pods" in API group "" in the namespace "kube-system"
-```
-

+The documentation for each chart is done with [helm-docs](https://github.com/norwoodj/helm-docs). This way we can ensure that values are consistent with the chart documentation.
+
+We have a script on the repository which will execute the helm-docs docker container, so that you don't have to worry about downloading the binary etc. Simply execute the script (Bash compatible):
 
 ```
-$ make remove
+bash scripts/helm-docs.sh
 ```

 ## Notes on installing Custom Resource Definitions with Helm3
 
 Capsule, as many other add-ons, defines its own set of Custom Resource Definitions (CRDs). Helm3 removed the old CRDs installation method for a more simple methodology. In the Helm Chart, there is now a special directory called `crds` to hold the CRDs. These CRDs are not templated, but will be installed by default when running a `helm install` for the chart. If the CRDs already exist (for example, you already executed `helm install`), it will be skipped with a warning. When you wish to skip the CRDs installation, and do not see the warning, you can pass the `--skip-crds` flag to the `helm install` command.
 
+## Cert-Manager integration
+
+You can enable the generation of certificates using `cert-manager` as follows.
+
+```
+helm upgrade --install capsule clastix/capsule --namespace capsule-system --create-namespace \
+  --set "certManager.generateCertificates=true" \
+  --set "tls.create=false" \
+  --set "tls.enableController=false"
+```
+
+With the usage of `tls.enableController=false` value, you're delegating the injection of the Validating and Mutating Webhooks' CA to `cert-manager`.
+Since Helm3 doesn't allow to template _CRDs_, you have to patch manually the Custom Resource Definition `tenants.capsule.clastix.io` adding the proper annotation (YMMV).

+# Deploying the Capsule Operator
+
+Use the Capsule Operator for easily implementing, managing, and maintaining multitenancy and access control in Kubernetes.
+
+## Requirements
+
+* [Helm 3](https://github.com/helm/helm/releases) is required when installing the Capsule Operator chart. Follow Helm’s official [steps](https://helm.sh/docs/intro/install/) for installing helm on your particular operating system.
+
+* A Kubernetes cluster 1.16+ with following [Admission Controllers](https://kubernetes.io/docs/reference/access-authn-authz/admission-controllers/) enabled:
+
+    * PodNodeSelector
+    * LimitRanger
+    * ResourceQuota
+    * MutatingAdmissionWebhook
+    * ValidatingAdmissionWebhook
+
+* A [`kubeconfig`](https://kubernetes.io/docs/concepts/configuration/organize-cluster-access-kubeconfig/) file accessing the Kubernetes cluster with cluster admin permissions.
+
+## Quick Start
+
+The Capsule Operator Chart can be used to instantly deploy the Capsule Operator on your Kubernetes cluster.
+
+1. Add this repository:
+
+        $ helm repo add clastix https://clastix.github.io/charts
+
+2. Install the Chart:
+
+        $ helm install capsule clastix/capsule -n capsule-system --create-namespace
+
+3. Show the status:
+
+        $ helm status capsule -n capsule-system
+
+4. Upgrade the Chart
+
+        $ helm upgrade capsule clastix/capsule -n capsule-system
+
+5. Uninstall the Chart
+
+        $ helm uninstall capsule -n capsule-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 install capsule capsule-helm-chart --values myvalues.yaml -n capsule-system
+
+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 install capsule capsule-helm-chart --set manager.options.forceTenantPrefix=false -n capsule-system
+
+Here the values you can override:
