The Magento demo is purely for demo purposes. If you intend to begin working in Magento on catalog and orders you will need to spin up your own instance of Magento (or desired backend).

Hi rain20
thanks for clarification, i was following the below doc
https://docs.vuestorefront.io/guide/cookbook/data-import.html#_2-2-recipe-b-using-on-premise
, now understood before this we need Megento or any other backend running before reaching to this step .
