+The Scaleway File Storage Container Storage Interface (CSI) driver enables Kubernetes users to manage Scaleway File Storage volumes within their clusters.  
 The Scaleway File Storage CSI driver is designed to work with Kubernetes Kapsule and Kosmos clusters, providing a standardized interface to create, manage, and attach file storage volumes to your containerized workloads. For more details on Scaleway File Storage, refer to the [Scaleway File Storage documentation](https://www.scaleway.com/en/file-storage/).

 ## Using the Scaleway File Storage CSI Driver
 
-The Scaleway File Storage CSI driver supports dynamic provisioning of Persistent Volumes (PVs) and Persistent Volume Claims (PVCs) in Kubernetes. Below are examples of how to use the driver to create and manage file storage volumes.
+The CSI driver supports dynamic provisioning of Persistent Volumes (PVs) and Persistent Volume Claims (PVCs).
 
 ### Creating a Persistent Volume Claim (PVC)
 
-This example demonstrates how to create a PVC to dynamically provision a Scaleway File Storage volume and use it in a pod.
-
-1. Create a file named `pvc.yaml` with the following content:
+1. Create a file named `pvc.yaml`:
 
    ```yaml
    apiVersion: v1
    kind: PersistentVolumeClaim
    metadata:
-     name: my-file-pvc
+     name: my-pvc
    spec:
      accessModes:
        - ReadWriteMany
      resources:

-     storageClassName: scaleway-file-default

    ```
 
-   Apply the PVC:
+   Apply it:
+
    ```bash
    kubectl apply -f pvc.yaml
    ```
 
-2. Create a file named `pod.yaml` to define a pod that uses the PVC:
+2. Create a file named `pod.yaml`:
 
    ```yaml
    apiVersion: v1
    kind: Pod
    metadata:
-     name: my-file-app
+     name: my-app
    spec:
      containers:
-     - name: busybox
-       image: busybox
-       command: ["sleep", "3600"]
-       volumeMounts:
-       - mountPath: "/data"
-         name: file-volume
+       - name: my-busybox
+         image: busybox
+         volumeMounts:
+           - name: my-volume
+             mountPath: "/data"
+         command: ["/bin/sh", "-c"]
+         args: ["tail -f /dev/null"]
      volumes:
-     - name: file-volume

+       - name: my-volume
+         persistentVolumeClaim:
+           claimName: my-pvc
    ```
 
    Apply the pod configuration:
+
    ```bash
    kubectl apply -f pod.yaml
    ```
 
-3. Check that the pod is running and the volume is mounted:
+3. Verify the mount:
+
    ```bash
    kubectl get pods
-   kubectl exec -it my-file-app -- df -h /data
+   kubectl exec -it my-app -- df -h /data
    ```
 
-   The output should show the mounted Scaleway File Storage volume at `/data`.

 ### Importing an existing File Storage volume
 
-You can import an existing Scaleway File Storage volume into Kubernetes using the Scaleway File Storage CSI driver. This is useful for integrating pre-existing storage volumes into your cluster.

    ```
 
-   Apply the storage class:
+   Apply:
+
    ```bash

+2. Update the PVC to use this storage class:
 
    ```yaml
    apiVersion: v1

+     name: my-pvc
    spec:
      accessModes:
        - ReadWriteMany
      resources:
        requests:
-         storage: 10Gi
-     storageClassName: my-file-storage-class
-   ```
-
-   Apply the PVC:

-   kubectl apply -f pvc.yaml
+         storage: 100Gi
