Head over to the settings page to set the store title.
This is used to help customise the appearance of the downloaded files. Some user wish to add a title to the front of the downloaded ZIP file thats made automatically to deliver the manuals to the user.
By default we will name this Zip file,
'variant sku' - 'product title' - 'variant-title'.zip
But some users may want to to display with a store title at the beginning, for example...
MyStore - 'variant sku' - 'product title' - 'variant-title'.zip
