+## Testing locally with kind
+
+Our makefile contains targets to test your current version of kube-bench inside a [Kind](https://kind.sigs.k8s.io/) cluster. This can be very handy if you don't want to run a real Kubernetes cluster for development purposes.
+
+First, you'll need to create the cluster using `make kind-test-cluster` this will create a new cluster if it cannot be found on your machine. By default, the cluster is named `kube-bench` but you can change the name by using the environment variable `KIND_PROFILE`.
+
+*If kind cannot be found on your system the target will try to install it using `go get`*
+
+Next, you'll have to build the kube-bench docker image using `make build-docker`, then we will be able to push the docker image to the cluster using `make kind-push`.
+
+Finally, we can use the `make kind-run` target to run the current version of kube-bench in the cluster and follow the logs of pods created. (Ctrl+C to exit)
+
+Every time you want to test a change, you'll need to rebuild the docker image and push it to cluster before running it again. ( `make build-docker kind-push kind-run` )
+
+To run the STIG tests locally execute the following: `make build-docker kind-push kind-run-stig`

-## Installation
+## CIS Scanning as part of Trivy and the Trivy Operator
 
-You can either install kube-bench through a dedicated container, or compile it from source:
+[Trivy](https://github.com/aquasecurity/trivy), the all in one cloud native security scanner, can be deployed as a [Kubernetes Operator](https://github.com/aquasecurity/trivy-operator) inside a cluster.
+Both, the [Trivy CLI](https://github.com/aquasecurity/trivy), and the [Trivy Operator](https://github.com/aquasecurity/trivy-operator) support CIS Kubernetes Benchmark scanning among several other features.
 
-1. Container installation:
-Run ```docker run --rm -v `pwd`:/host aquasec/kube-bench:latest```. This will copy the kube-bench binary and configuration to you host. You can then run ```./kube-bench <master|node>```.
+## Quick start
 
-2. Install from sources:
-If Go is installed on the target machines, you can simply clone this repository and run as follows: 
-```go get github.com/aquasecurity/kube-bench```
-```cp $GOROOT/bin/kube-bench .```
-```./kube-bench <master|node>```
+There are multiple ways to run kube-bench.
+You can run kube-bench inside a pod, but it will need access to the host's PID namespace in order to check the running processes, as well as access to some directories on the host where config files and other files are stored.
 
-## Usage
-```./kube-bench [command]```
+The supplied `job.yaml` [file](job.yaml) can be applied to run the tests as a job. For example:
 
-```
-Available Commands:
-  federated   Run benchmark checks for a Kubernetes federated deployment.
-  help        Help about any command
-  master      Run benchmark checks for a Kubernetes master node.
-  node        Run benchmark checks for a Kubernetes node.
+```bash
+$ kubectl apply -f job.yaml
+job.batch/kube-bench created
 
-Flags:
-  -c, --check string          A comma-delimited list of checks to run as specified in CIS document. Example --check="1.1.1,1.1.2"
-      --config string         config file (default is ./cfg/config.yaml)
-  -g, --group string          Run all the checks under this comma-delimited list of groups. Example --group="1.1"
-      --installation string   Specify how kubernetes cluster was installed. Possible values are default,hyperkube,kops,kubeadm (default "default")
-      --json                  Prints the results as JSON
-  -v, --verbose               verbose output (default false)
-```
+$ kubectl get pods
+NAME                      READY   STATUS              RESTARTS   AGE
+kube-bench-j76s9   0/1     ContainerCreating   0          3s
 
-## Configuration
-Kubernetes config and binary file locations and names can vary from installation to installation, so these are configurable in the `cfg/config.yaml` file. 
+# Wait for a few seconds for the job to complete
+$ kubectl get pods
+NAME                      READY   STATUS      RESTARTS   AGE
+kube-bench-j76s9   0/1     Completed   0          11s
 
-They also tend to vary according to which tool was used to install Kubernetes. You can use the `--installation` flag to pick up a different default set of file names and locations. Again these defaults are configurable through `cfg/config.yaml` (and pull requests to correct or add default file locations are especially welcome). 
-
-## Test config YAML representation
-The tests are represented as YAML documents (installed by default into ./cfg).
-
-An example is as listed below:
-```
----
-controls:
-id: 1
-text: "Master Checks"
-type: "master"
-groups:
-- id: 1.1
-  text: "Kube-apiserver"
-  checks:
-    - id: 1.1.1
-      text: "Ensure that the --allow-privileged argument is set (Scored)"
-      audit: "ps -ef | grep kube-apiserver | grep -v grep"
-      tests:
-      bin_op: or
-      test_items:
-      - flag: "--allow-privileged"
-        set: true
-      - flag: "--some-other-flag"
-        set: false
-      remediation: "Edit the /etc/kubernetes/config file on the master node and set the KUBE_ALLOW_PRIV parameter to '--allow-privileged=false'"
-      scored: true
-```
-
-Recommendations (called `checks` in this document) can run on Kubernetes Master, Node or Federated API Servers.
-Checks are organized into `groups` which share similar controls (things to check for) and are grouped together in the section of the CIS Kubernetes document.
-These groups are further organized under `controls` which can be of the type `master`, `node` or `federated apiserver` to reflect the various Kubernetes node types.
-
-## Tests
-Tests are the items we actually look for to determine if a check is successful or not. Checks can have multiple tests, which must all be successful for the check to pass.
-
-The syntax for tests:
-```
-tests:
-- flag:
-  set:
-  compare:
-    op:
-    value:
+# The results are held in the pod's logs
+kubectl logs kube-bench-j76s9
+[INFO] 1 Master Node Security Configuration
+[INFO] 1.1 API Server
 ...
 ```
-Tests have various `operations` which are used to compare the output of audit commands for success.
-These operations are:
+For more information and different ways to run kube-bench see [documentation](docs/running.md)
+### Please Note
 
-- `eq`: tests if the flag value is equal to the compared value.
-- `noteq`: tests if the flag value is unequal to the compared value.
-- `gt`: tests if the flag value is greater than the compared value.
-- `gte`: tests if the flag value is greater than or equal to the compared value.
-- `lt`: tests if the flag value is less than the compared value.
-- `lte`: tests if the flag value is less than or equal to the compared value.
-- `has`: tests if the flag value contains the compared value.
-- `nothave`: tests if the flag value does not contain the compared value.
+1. kube-bench implements the [CIS Kubernetes Benchmark](https://www.cisecurity.org/benchmark/kubernetes/) as closely as possible. Please raise issues here if kube-bench is not correctly implementing the test as described in the Benchmark. To report issues in the Benchmark itself (for example, tests that you believe are inappropriate), please join the [CIS community](https://cisecurity.org).
 
-# Roadmap 
-The tests are up-to-date with the CIS Benchmark 1.1.0, which refers to Kubernetes 1.7. Going forward we should release updates to kube-bench to reflect new releases of the Benchmark, which in turn we can anticipate being made for each new Kubernetes release. 
+1. There is not a one-to-one mapping between releases of Kubernetes and releases of the CIS benchmark. See [CIS Kubernetes Benchmark support](docs/platforms.md#cis-kubernetes-benchmark-support) to see which releases of Kubernetes are covered by different releases of the benchmark.
+
+
+By default, kube-bench will determine the test set to run based on the Kubernetes version running on the machine.
+- see the following documentation on [Running kube-bench](docs/running.md#running-kube-bench) for more details.

+
+## Roadmap
+
+Going forward we plan to release updates to kube-bench to add support for new releases of the CIS Benchmark. Note that these are not released as frequently as Kubernetes releases.

+          Azure Active Directory integration
+          The security of AKS clusters can be enhanced with the integration of Azure Active Directory
+          (AD). Built on decades of enterprise identity management, Azure AD is a multi-tenant,
+          cloud-based directory, and identity management service that combines core directory
+          services, application access management, and identity protection. With Azure AD, you can
+          integrate on-premises identities into AKS clusters to provide a single source for account
+          management and security.
+          Azure Active Directory integration with AKS clusters
+          With Azure AD-integrated AKS clusters, you can grant users or groups access to Kubernetes
+          resources within a namespace or across the cluster. To obtain a kubectl configuration
+          context, a user can run the az aks get-credentials command. When a user then interacts
+          with the AKS cluster with kubectl, they're prompted to sign in with their Azure AD
+          credentials. This approach provides a single source for user account management and
+          password credentials. The user can only access the resources as defined by the cluster
+          administrator.
+          Azure AD authentication is provided to AKS clusters with OpenID Connect. OpenID Connect
+          is an identity layer built on top of the OAuth 2.0 protocol. For more information on OpenID
+          Connect, see the Open ID connect documentation. From inside of the Kubernetes cluster,
+          Webhook Token Authentication is used to verify authentication tokens. Webhook token
+          authentication is configured and managed as part of the AKS cluster.
