Wedding Program Wording Catholic

How can you write a program of Catholic marriage, if you have two priests at the altar – a main and auxiliary officiating?

I married in a few weeks (Catholic Church). Basically, we have a director and other officiating priest (who had to be in the parish until he moved) help too – I've talked to a senior officer and is glad to have another priest at the altar as well. My question is really about how we make the wording the ceremony because there were two priests. I thought senior officers, but do not know how to call another priest? Thank you! My family is active in the church and the knowledge of the priests to be asked separately (as friends of the family), but as priests on the altar. I'm just trying to understand the actual wording of the printed program.

O Celebrant: Father Father concelebrant ____ __ O: Celebrant: Father ____ ____ homily, Father use the first option if your principal celebrant the homily. If the second priest gave the homily, while the former priest in charge of almost everything else, use the second option.
