Hi bro, my advice
1. Consult your partner / both parents where & how you want to held you wedding
2. If the answer is church, be prepare to attend pre-marriage course 6 months before your marriage date. Watch out for announcement during mass. This course is normally held for 2-3 days only with minimum religious thing but more to life after marriage.
3. Consult the priest in your church on your wedding date. Priest may want to interview you and your partner before wedding day.
4. Catholic marrying non-catholic - not full mass so no holy communion.
5. On the wedding day sign the wedding cert at church and then priest will pronounce you Husband & Wife and your life will change FOREVER ..LOL.

Good Luck !
