After starting the New Governance Instance wizard select option 2, “From another one that you have developed”.
Give the new instance a name and select the template you desire from the drop-down.
If the dropdown is empty, that means you have not saved any of your existing instances as a template. See section 7.5 on how to save one of your existing instances as a template.
From this point, you follow the same steps that you would if you were creating a Bound instance from a Navvia template.
