+### Configuring a Worker for Self Hosted Cloud
+
+1. Create a Kubernetes secret for a Prefect Self Hosted Cloud API key
+
+    First create a file named `api-key.yaml` with the following contents:
+
+    ```yaml
+    apiVersion: v1
+    kind: Secret
+    metadata:
+      name: prefect-api-key
+      namespace: prefect
+    type: Opaque
+    data:
+      key:  <base64-encoded-api-key>
+    ```
+
+    Replace `<base64-encoded-api-key>` with your Prefect Self Hosted Cloud API key encoded in base64. The helm chart looks for a secret of this name and schema, this can be overridden in the `values.yaml`.
+
+    You can use the following command to generate the base64-encoded value:
+
+    ```bash
+    echo -n "your-prefect-self-hosted-cloud-api-key" | base64
+    ```
+
+    Then apply the `api-key.yaml` file to create the Kubernetes secret:
+
+    ```bash
+    kubectl apply -f api-key.yaml
+    ```
+
+    Alternatively, you can create the Kubernetes secret via the cli with the following command. In this case, Kubernetes will take care of base64 encoding the value on your behalf:
+
+    ```bash
+    kubectl create secret generic prefect-api-key --from-literal=key=pnu_xxxx
+    ```
+
+2. Configure the Prefect worker values
+
+    Create a `values.yaml` file to customize the Prefect worker configuration. Add the following contents to the file:
+
+    ```yaml
+    worker:
+      apiConfig: selfHosted
+      config:
+        workPool: <target work pool name>
+      selfHostedApiConfig:
+        apiUrl: "https://<DNS of Self Hosted Cloud API>"
+        accountId: <target account ID>
+        workspaceId: <target workspace ID>
+        uiUrl: "https://<DNS of Self Hosted Cloud UI>"
+    ```
+
+    These settings will ensure that the worker connects to the proper account, workspace, and work pool.
+    View your Account ID and Workspace ID in your browser URL when logged into Prefect Cloud. For example: `https://self-hosted-prefect.company/account/abc-my-account-id-is-here/workspaces/123-my-workspace-id-is-here`
