 ## Creating and registering the volumes
 
+### New way 
+
+To create the volume, use the nomad cli
+
+First create the following volume.hcl file
+```hcl
+
+id = "iscsi-volume-name"
+name = "iscsi-volume-name"
+type = "csi"
+plugin_id = "org.democratic-csi.iscsi"
+capacity_max = "2G"
+capacity_min = "1G"
+
+capability {
+  access_mode     = "single-node-writer"
+  attachment_mode = "file-system"
+}
+```
+
+Then apply from a server node:
+
+```
+nomad volume create volume.hcl
+```
+
+Or from gitlab CICD
+
+```
+create-csi-volume:
+  stage: deploy
+  image: hendrikmaus/nomad-cli
+  script:
+    - nomad volume create volume.hcl
+```
+
+### Old way
 To create the volumes, we are going to use the [csc](https://github.com/rexray/gocsi/tree/master/csc) utility. It can be installed via `go`.
