-Fairwinds' Polaris keeps your clusters sailing smoothly. It runs a variety of checks to ensure that
-Kubernetes pods and controllers are configured using best practices, helping you avoid
-problems in the future.
+Polaris is an open source policy engine for Kubernetes that validates and remediates resource configuration. It includes 30+ built in configuration policies, as well as the ability to build custom policies with JSON Schema. When run on the command line or as a mutating webhook, Polaris can automatically remediate issues based on policy criteria.
 
 Polaris can be run in three different modes:
-* As a [dashboard](https://polaris.docs.fairwinds.com/dashboard), so you can audit what's running inside your cluster.
-* As an [admission controller](https://polaris.docs.fairwinds.com/admission-controller), so you can automatically reject workloads that don't adhere to your organization's policies.
-* As a [command-line tool](https://polaris.docs.fairwinds.com/infrastructure-as-code), so you can test local YAML files, e.g. as part of a CI/CD process.
-
+* As a [dashboard](https://polaris.docs.fairwinds.com/dashboard) - Validate Kubernetes resources against policy-as-code.

 This means that any checks with a severity of `warning` will still pass webhook validation,
 and the only evidence of that warning will either be in the Polaris dashboard or the
 Polaris webhook logs. This will change in a future version of Kubernetes.
+
+## Mutating Webhook
+By default, the Admission Controller is just pass/fail, but
+Polaris can also operate as a mutating webhook for many of the issues it checks for.
+This means Polaris will remediate the issue it finds, rather than rejecting
+the deployment.
+
+To enable the mutating webhook, add `--set webhook.mutate=true` to your
+Helm installation command.
+
+The following default checks currently have mutation support enabled:
+* `hostPIDSet`
+* `hostNetworkSet`
+* `hostIPCSet`
+* `priorityClassNotSet`
+* `hostPortSet`
+* `pullPolicyNotAlways`
+* `deploymentMissingReplicas`
+* `dangerousCapabilities`
+* `cpuLimitsMissing`
+* `memoryLimitsMissing`
+* `livenessProbeMissing`
+* `memoryRequestsMissing`
+* `cpuRequestsMissing`
+* `runAsPrivileged`
+* `readinessProbeMissing`
+* `privilegeEscalationAllowed`
+* `notReadOnlyRootFilesystem`
+* `insecureCapabilities`
+* `runAsRootAllowed`
+
+If you'd like to
+enable other mutations, you can set the `webhook.mutations` flag.

 ## Background
 
+### Liveness and Readiness Probes
 Readiness and liveness probes can help maintain the health of applications running inside Kubernetes. By default, Kubernetes only knows whether or not a process is running, not if it's healthy. Properly configured readiness and liveness probes will also be able to ensure the health of an application.
 
 Readiness probes are designed to ensure that an application has reached a "ready" state. In many cases there is a period of time between when a webserver process starts and when it is ready to receive traffic. A readiness probe can ensure the traffic is not sent to a pod until it is actually ready to receive traffic.
 
 Liveness probes are designed to ensure that an application stays in a healthy state. When a liveness probe fails, the pod will be restarted.
 
+### Image Pull Policy
 Docker's `latest` tag is applied by default to images where a tag hasn't been specified. Not specifying a specific version of an image can lead to a wide variety of problems. The underlying image could include unexpected breaking changes that break your application whenever the latest image is pulled. Reusing the same tag for multiple versions of an image can lead to different nodes in the same cluster having different versions of an image, even if the tag is identical.
 
 Related to that, relying on cached versions of a Docker image can become a security vulnerability. By default, an image will be pulled if it isn't already cached on the node attempting to run it. This can result in variations in images that are running per node, or potentially provide a way to gain access to an image without having direct access to the ImagePullSecret. With that in mind, it's often better to ensure the a pod has `pullPolicy: Always` specified, so images are always pulled directly from their source.
 
+### Topology Spread Constraints
+
+By default, the Kubernetes scheduler uses a bin-packing algorithm to fit as many pods as possible into a cluster. The scheduler prefers a more evenly distributed general node load to app replicas precisely spread across nodes. Therefore, by default, multi-replica is not guaranteed to be spread across multiple availability zones. Kubernetes provides topologySpreadConstraint configuration in order to better ensure pod spread across multiple AZs and/or Hosts.
+
+Example of a topologySpreadConstraint spreading across zones:
+
+```
+apiVersion: apps/v1
+kind: Deployment
+metadata:
+  name: demo-basic-demo
+spec:
+  selector:
+    matchLabels:
+      app.kubernetes.io/name: basic-demo
+      app.kubernetes.io/instance: demo
+  template:
+    metadata:
+      labels:
+        app.kubernetes.io/name: basic-demo
+        app.kubernetes.io/instance: demo
+    spec:
+      topologySpreadConstraints:
+        - maxSkew: 1
+          topologyKey: "topology.kubernetes.io/zone"
+          whenUnsatisfiable: ScheduleAnyway

+
+to fix any issues inside the `deploy` directory. Polaris may leave
+comments next to some changes (e.g. liveness and readiness probes) prompting
+the user to set them to something more appropriate given the context of their
+application.
+
+Note that not all issues can be automatically fixed.
+
+Currently only raw YAML manifests can be mutated. Helm charts etc.
+still need to be changed manually.
