The First step to configuring a Configuration Template, is to Configure one Login Portal that you want to reuse on other Venues.
Select the Venue from the Organization Dropdown.
Go to the Login Portal, and configure the look and feel of the page, along with the Connection Methods you want to use and your registration Form Fields.
Once this is done, on the right of the top Save button, click on the Button with the 3 dots, then select Allow reusing Config as a Template.
After doing that, a new Template Dropdown will appear that tell you how many networks are using this Template.
