How do I add my custom fields to the Job Listing Page

I’m trying to add all of the custom fields that we’ve added to our Listings, but I have no idea how to do it. Can you please point me to the documentation that explains this? Or, please tell us how to do it.

Also, we will want people who are Non-Members to be able to see just a few specific fields. In order to see everything and bid on a job, they will have to have a membership.

Can you help us in setting this up as well?
