+1. Run the command below to list your Block Storage volumes. Do not forget to replace the `{zone}` placeholder with the desired Availability Zone (`fr-par-1`, `nl-ams-2`, etc.):
+    ```
+    curl -X GET \
+    -H "X-Auth-Token: $SCW_SECRET_KEY" \
+    "https://api.scaleway.com/block/v1alpha1/zones/{zone}/volumes"

+    An output similar to the following displays:
+
+    ```

+    ```
+
+2. To modify the volume size, run the request below. Do not forget to replace the placeholders with the appropriate value:
+    ```
+    curl -X PATCH \
+    -H "X-Auth-Token: $SCW_SECRET_KEY" \
+    -H "Content-Type: application/json" \
+    -d '{"size" : "{size_in_bytes}"}' \

+    ```
+    <Message type="note">
+    You can only increase the size of a Block Storage volume. Reducing its size is not permitted due to technical constraints.
