Let's walk you through it. When the template is ready to go live and well-tested by the admins, it's ready to live.
How to set a template live
Change the template status from 'Inactive' to 'Active'. You can do this in the top right corner under 'Status' when editing a template.
Navigate to the product and activate the module 'Templates'.
All temples with 'Active' status will be visible in the dropdown under 'Template ID'. The dropdown shows all active templates in a new to old order.
