 Steps to setup an arduino device:
 - arduino device is provisioned, information about its future location are passed as tags: 
-  `$ arduino-cloud-cli device create -n LedDevice --tags location=Milan,room=101,floor=1`
+  `$ arduino-cloud-cli device create -n LedDevice101 --tags location=Milan,room=101,floor=1`
 - thing is created starting from the thing template and bound to the device: 
   `$ arduino-cloud-cli thing create -n LedThing101 -t LedThingTemplate.yaml `
   `$ arduino-cloud-cli thing bind -i <thingID> -d <deviceID>`
 - dashboard is created overriding the thing placeholder with the actual thing id:
   `$ arduino-cloud-cli dashboard create -n LedDashboard101 -t LedDashboardTemplate.yaml --override LedThing=<thingID>`
 - The sketch is uploaded to the device
 
-This steps should be repeated for every arduino device. 
+This steps should be repeated for every arduino device. So, for example, another device in a different room could be provisioned with:   `$ arduino-cloud-cli device create -n LedDevice102 --tags location=Milan,room=102,floor=1`
 
 When the customer wants to update the firmware of the devices, he can use the ota command specifying the tags of the devices to be updated:
-  `$ arduino-cloud-cli ota upload --file <newFirmware.bin> --device-tags floor=2`
+  `$ arduino-cloud-cli ota upload --file <newFirmware.bin> --device-tags floor=1`
+In this case both the devices LedDevice101 and LedDevice102 will be updated.
