First, download the demo content as zip from the download link you received after purchase. Inside the ZIP, you can find a `production.tar.gz` file which you should move to the `yourProject/studio` folder.
You can import data to your sanity studio by using Sanity CLI. To run, open the studio path in the terminal by running
cd studio and then run the following command.
sanity dataset import production.tar.gz production
This step is optional, but recommended because otherwise, without any data, you cannot run front-end as it will throw errors. You can delete or modify the data later once you are done with customization.
