How To Get Married

My Fiancée and I want to get legally married but we are going to wait to have a ceremony.

I know we have to go to Metro Hall to get a marriage license, we plan to bring a few witnesses and my ordained pagan friend to marry us (we are pagans also) and sign the license while we are in the clerks office, but what do we do after that?

I tried looking up more updated steps but everything ive found on the city websites isnt mind of vague and requires phone calls to be made ans everything on this subreddit on the topic is from 8 years ago when they still did a lot of that stuff at the Hall of Justice.

any help is appreciated. thank you. sorry if its a dumb question, never done this before.
