How do I pay for an FF14 account

Howdy yall. I am trying to figure out how to apply crysta to my account to pay for my subscription. I bought the crysta but I can't find out how to apply it to my account. I know this isn't an in game new player issue but it is an issue for a new player.

I am not familiar with Crysta too much, but there is an option through your subscription management over on the Mog Station to pay with Crysta.
