+## About Kubernetes admission controller
+
+[Artifact attestations](/actions/security-guides/using-artifact-attestations-to-establish-provenance-for-builds) enable you to create unfalsifiable provenance and integrity guarantees for the software you build. In turn, people who consume your software can verify where and how your software was built.
+
+Kubernetes admission controllers are plugins that govern the behavior of the Kubernetes API server. They are commonly used to enforce security policies and best practices in a Kubernetes cluster.
+
+Using the open source [Sigstore Policy Controller](https://docs.sigstore.dev/policy-controller/overview/) project you can add an admission controller to your Kubernetes cluster that can enforce artifact attestations. This way, you can ensure that only artifacts with valid attestations can be deployed.
+
+To [install the controller](#getting-started-with-kubernetes-admission-controller), we offer [two Helm charts](https://github.com/github/artifact-attestations-helm-charts): one for deploying the Sigstore Policy Controller, and another for loading the GitHub trust root and a default policy.
+
+### About trust roots and policies
+
+The Sigstore Policy Controller is primarily configured with trust roots and policies, represented by the Custom Resources `TrustRoot` and `ClusterImagePolicy`. A `TrustRoot` represents a trusted distribution channel for the public key material used to verify attestations. A `ClusterImagePolicy` represents a policy for enforcing attestations on images.
+
+A `TrustRoot` may also contain a [TUF](https://theupdateframework.io/) repository root, making it possible for your cluster to continuously and securely receive updates to its trusted public key material. If left unspecified, a `ClusterImagePolicy` will by default use the open source Sigstore Public Good Instance's key material. When verifying attestations generated for private repositories, the `ClusterImagePolicy` must reference the GitHub `TrustRoot`.
+
+## Getting started with Kubernetes admission controller
+
+To set up an admission controller for enforcing GitHub artifact attestations, you need to:
+
+1. [Deploy the Sigstore Policy Controller](#deploy-the-sigstore-policy-controller).
+1. [Add the GitHub `TrustRoot` and a `ClusterImagePolicy` to your cluster](#add-the-github-trustroot-and-a-clusterimagepolicy).
+1. [Enable the policy in your namespace](#enable-the-policy-in-your-namespace).
+
+### Deploy the Sigstore Policy Controller
+
+We have packaged the Sigstore Policy Controller as a [GitHub distributed Helm chart](https://github.com/github/artifact-attestations-helm-charts). Before you begin, ensure you have the following prerequisites:
+
+* A Kubernetes cluster with version 1.27 or later
+* [Helm](https://helm.sh/docs/intro/install/) 3.0 or later
+* [kubectl](https://kubernetes.io/docs/tasks/tools/)
+
+First, install the Helm chart that deploys the Sigstore Policy Controller:
+
+```bash copy
+helm install policy-controller --atomic \
+  --create-namespace --namespace artifact-attestations \
+  oci://ghcr.io/github/artifact-attestations-helm-charts/policy-controller \
+  --version v0.9.0-github3
+```
+
+This installs the Policy Controller into the `artifact-attestations` namespace. At this point, no policies have been configured, and it will not enforce any attestations.
+
+### Add the GitHub `TrustRoot` and a `ClusterImagePolicy`
+
+Once the policy controller has been deployed, you need to add the GitHub `TrustRoot` and a `ClusterImagePolicy` to your cluster. Use the Helm chart we provide to do this. Make sure to replace `MY-ORGANIZATION` with your GitHub organization's name (e.g., `github` or `octocat-inc`).
+
+```bash copy
+helm install trust-policies --atomic \
+ --namespace artifact-attestations \
+ oci://ghcr.io/github/artifact-attestations-helm-charts/trust-policies \
+ --version v0.4.0 \
+ --set policy.enabled=true \
+ --set policy.organization=MY-ORGANIZATION
+```
+
+You've now installed the GitHub trust root, and an artifact attestation policy into your cluster. This policy will reject artifacts that have not originated from within your GitHub organization.
+
+### Enable the policy in your namespace
+
+> [!WARNING]
+> This policy will not be enforced until you specify which namespaces it should apply to.
+
+Each namespace in your cluster can independently enforce policies. To enable enforcement in a namespace, you can add the following annotation to the namespace:
+
+```yaml
+metadata:
+  annotations:
+    policy.sigstore.dev/include: true
+```
+
+After the annotation is added, the GitHub artifact attestation policy will be enforced in the namespace.
+
+Alternatively, you may run:
+
+```bash copy
+kubectl label namespace MY-NAMESPACE policy.sigstore.dev/include=true
+```
+
+### Advanced usage
+
+To see the full set of options you may configure with the Helm chart, you can run either of the following commands.
+For policy controller options:
+
+```bash copy
+helm show values oci://ghcr.io/github/artifact-attestations-helm-charts/policy-controller --version v0.9.0-github3
+```
+
+For trust policy options:
+
+```bash copy
+helm show values oci://ghcr.io/github/artifact-attestations-helm-charts/trust-policies --version v0.4.0
+```
+
+For more information on the Sigstore Policy Controller, see the [Sigstore Policy Controller documentation](https://docs.sigstore.dev/policy-controller/overview/).
