CSV Import for Responsive Directory Theme

Is there a sample CSV file that we can download showing us how to upload listings into the Responsive Directory Theme?

The three standard fields are listing title, description and categories, what are the proper fields for this?

I am particularly not clear on how do you assign categories and sub-categories, any help here?

can you also assign listings to users automatically during the import process?

Can you also assign listings packages within the CSV?

I think a better CSV file template should be made available to us!
