How to use a domain hosted elsewhere
From the left, click on Online Store.
Click on the Domain section.
Click on Domain redirection.
Enter the address in the field (for example www.yourstoresname.fi)
On the right-hand side of the page, you will see a Required Name Service Changes section. Take note of the instructions there. You can use them to redirect the domain name to your store. Your domain administrator will provide further guidance if necessary.
