-This guide walks you through setting up Newt on Kubernetes using Helm.
-
-This guide assumes you already are familiar with Kubernetes concepts and you fulfill the following Global prerequisites:
-
-## Global Prerequisites
-
-- Kubernetes Cluster (v1.28.15+)
-- Access to the Kubernetes Cluster
-- Helm (v3.0+) installed, see <Link href="https://helm.sh/docs/intro/install/">Helm install docs</Link>
-
-## Helm Installation
-
-All Fossorial Helm charts are available on Artifact Hub. See <Link href="https://artifacthub.io/packages/search?org=fosrl">Fossorial Charts</Link>.
-
-<Steps>
-  <Step title="Add Fossorial Helm repo">
-    ```bash
-    helm repo add fossorial https://charts.fossorial.io
-    helm repo update fossorial
-    helm search repo fossorial
-    ```
-  </Step>
-  <Step title="Prepare Installation files">
-
-	Prepare your Newt credentials:
-    ```env title="newt-cred.env"
-	PANGOLIN_ENDPOINT=<your-endpoint>
-	NEWT_ID=<your-id>
-	NEWT_SECRET=<your-secret>
-	```
-
-    Prepare a values file with your desired configuration.
-
-	<Tip>See <Link href="https://github.com/fosrl/helm-charts/tree/main/charts/newt">Newt chart values configuration options</Link>.</Tip>
-
-    ```yaml title="values-newt.yaml"
-    newtInstances:
-      - name: main
-        enabled: true
-        auth:
-          existingSecretName: newt-cred
-          keys:
-            endpointKey: PANGOLIN_ENDPOINT
-            idKey: NEWT_ID
-            secretKey: NEWT_SECRET
-    ```
-	</Step>
-	<Step title="Newt Installation">
-
-    Create a Kubernetes Secret from the env file created earlier:
-	```bash
-kubectl create secret generic newt-cred -n newt --from-env-file=newt-cred.env
-	```
-
-	Install Newt with Helm:
-    ```bash
-    helm install my-newt fossorial/newt \
-      -n newt --create-namespace \
-      -f values-newt.yaml
-    ```
-
-	Change the release name (`my-newt`), namespace (`newt`), and values filename as needed.
-  </Step>
-  <Step title="Upgrade or rollback">
-    ```bash
-	# Update repo to get latest charts
-	helm repo update fossorial
-	# Upgrade Newt (after editing values)
-    helm upgrade my-newt fossorial/newt -n newt -f values-newt.yaml
-    ```
-	```bash
-	# Roll back to a previous revision
-    helm rollback my-newt 1 -n newt
-    ```
-  </Step>
-</Steps>
-
-## Customizing Your Values
