+The ngrok [Ingress Controller for Kubernetes](https://github.com/ngrok/kubernetes-ingress-controller) adds public and
+secure ingress traffic to Kubernetes applications. This open-source [Ingress
+Controller](https://kubernetes.io/docs/concepts/services-networking/ingress-controllers) works with Palette to provide
+ingress to your applications, APIs, or other resources while also offloading network ingress and middleware execution to
+ngrok's platform.
+
+# Versions Supported
+
+- 0.9.0
+
+## Prerequisites
+
+- An active [ngrok account](https://ngrok.com/signup).
+  - An ngrok authentication token. You can find your token in the dashboard. Visit the [**Your Authtoken**](https://dashboard.ngrok.com/get-started/your-authtoken) section to review your access token.
+  - An ngrok API key. You can generate an API key from the ngrok dashboard. Visit the [**API** section](https://dashboard.ngrok.com/api) of the dashboard to review existing keys.
+- A static subdomain. You can obtain a static subdomain by navigating to the [**Domains**
+section](https://dashboard.ngrok.com/cloud-edge/domains) of the ngrok dashboard and clicking on **Create Domain** or **New Domain**.
+
+## Parameters
+
+To deploy the ngrok Ingress Controller, you need to set, at minimum, the following parameters in the pack's YAML.
+
+| Name  | Description |
+| --- | --- |
+| `kubernetes-ingress-controller.credentials.apiKey` | Your ngrok API key for this application and domain. |
+| `kubernetes-ingress-controller.credentials.authtoken` | The authentication token for your active ngrok account. |
+| `kubernetes-ingress-controller.rules.host` | A static subdomain hosted by ngrok and associated with your account. |
+| `kubernetes-ingress-controller.rules.http.paths.path` | The path at which to route traffic to your application. For more advanced configurations, you can set multiple paths with corresponding `pathType`, `backend.service.name`, and `backend.service.name` parameters. |
+| `kubernetes-ingress-controller.rules.host.paths.pathType` | Specify how ingress paths should be [matched by type](https://kubernetes.io/docs/concepts/services-networking/ingress/#path-types). `Prefix` matches based on a URL path prefix split by `/`. `Exact` matches the URL path exactly and with case sensitivity. |
+| `kubernetes-ingress-controller.rules.host.backend.service.name` | The name you've given to the application for which the ngrok Ingress Controller should handle traffic. |
+| `kubernetes-ingress-controller.rules.host.backend.service.port.number` | The port number for the deployed `service.name`. |
+
+Review the [common overrides](https://github.com/ngrok/kubernetes-ingress-controller/blob/main/docs/deployment-guide/common-helm-k8s-overrides.md) document for more details on parameters. Refer to the [user guide](https://github.com/ngrok/kubernetes-ingress-controller/tree/main/docs/user-guide) for advanced configurations.
+
+:::caution
+
+If you have a free ngrok account, you can only have one ngrok agent active at a time. This means that you will need to set the number of replicas to `1` to ensure that your ngrok agent operates properly.
+
+```yaml
+charts:
+  kubernetes-ingress-controller:
+    replicaCount: 1
+```
+
+:::
+
+## Usage
+
+To use the ngrok Ingress Controller pack, first create a new [add-on cluster profile](../cluster-profiles/create-add-on-profile.md), search for the **ngrok Ingress Controller** pack, and overwrite the default pack configuration with your API key and authentication token like the following example YAML content:
+
+```yaml
+charts:  
+  kubernetes-ingress-controller:
+    ...
+    credentials:
+      apiKey: API_KEY
+      authtoken: AUTHTOKEN
+```
+
+Next, you must create an ingress service definition for your application, which requires a new manifest layer. Click on the **Add Manifest** button to create a new manifest layer. 
+
+The following YAML content demonstrates an example ingress service where the ngrok Ingress Controller creates a new edge to route traffic on your ngrok subdomain `example.com` to an existing `example-app` deployed on your Kubernetes cluster in Palette.
+
+```yaml
+apiVersion: networking.k8s.io/v1
+kind: Ingress
+metadata:
+  name: example-ingress
+  namespace: ngrok-ingress-controller
+spec:
+  ingressClassName: ngrok
+  rules:
+    - host: example.com
+      http:
+        paths:
+          - path: /
+            pathType: Prefix
+            backend:
+              service:
+                name: example-app
+                port:
+                  number: 80
+```
+
+Once you have defined the ngrok Ingress Controller pack, you can add it to an existing cluster profile, as an add-on profile, or as a new add-on layer to a deployed cluster.
+
+## Terraform
+
+You can reference the ngrok Ingress Controller pack in Terraform with a data resource.
+
+```
+data "spectrocloud_registry" "public_registry" {
+  name = "Public Repo"
+}
+data "spectrocloud_pack_simple" "ngrok-ingress" {
+  name    = "ngrok-ingress-controller"
+  version = "0.9.0"
+  type = "operator-instance"
+  registry_uid = data.spectrocloud_registry.public_registry.id
+}
+```
