+#### Create Google Cloud Storage Bucket
+

+2. **Open Cloud Storage**: Navigate to "Storage" > "Browser" in the left-side menu.
+3. **Create Bucket**: Click on "Create bucket". Give your bucket a unique name, select a region for the bucket, and configure other settings such as storage class and access control according to your requirements. Finally, click "Create".

+
+#### Create a Kubernetes Secret
+
+- Use the **`kubectl create secret`** command to create a Kubernetes secret from the JSON key file. Replace **`<secret-name>`** with the desired name for your secret, **`<path-to-json-key-file>`** with the path to the JSON key file you downloaded, and **`<namespace>`** with the namespace where your deployment will be running.
+
+```kubectl create secret generic <mysecret>  --from-file=gcp.json=</location/to/secret.json> --namespace=<namespace>```
+
+#### Create an extra Volume where the GCSFS secret will be added in the values.yaml inside of the worker section
+```
+worker:
+  extraVolumes:
+    - name: gcsfs-creds
+      secret:
+        secretName: <secret name>
+  extraVolumeMounts:
+    - name: gcsfs-creds
+      mountPath: "/etc/secrets"
+      readOnly: true
+```
+
+#### Update the values.yaml with the GCS Logging Information below
+Update the following Environment Variables in the global section:
+```
+global:
+ state:
+   storage:
+     type: "GCS"
+

 ### External Airbyte Database
 
 
-::info
+
+:::info
 This was tested using [Airbyte Helm Chart Version 0.50.13](https://artifacthub.io/packages/helm/airbyte/airbyte/0.50.13).
 Previous or newer version can change how the external database can be configured.

 The Airbyte Database only works with Postgres 13.
 Make sure the database is accessible inside the cluster using `busy-box` service using `telnet` or `ping` command.
