To start adding content you'll first want to add, "Sub-Stores" to your Studio. Go to your, "My Sub-Stores" Tab ---> click "+ Add a Sub-Store".
Once you add your "Sub-Store" your request will then be forwarded to our Artist Experience Team which will then approve it and issue you FTP credentials. You can find your FTP credentials in your "Sell Items" tab.
It's important to note that your sub-stores house the content that your customer will see on the site. You can have as many sub-stores as you would like, this provides you with the convenience of having one set of login credentials so you don't have to login to each seperate sub-store.
