Hi Ed,
There are 2 configuration files (.JXL) that comes with the install of Workflow Manager. During post installation you can choose to import the minimum config (contains what you need to use the application) or quick start config (contains examples of workflow/job types/user/groups).
You can still import this to your repository from the Administrator by simply right clicking you Workflow Manager database after connecting to it and import configuration. Browse to <Install location>\config\Database Configurations
Hope this helps!
