Oly

So I need some help. I am lvl 88 and my dual is 85 and I'm noble. I don't know how to do oly. Is there a quest I need to do so I can register and participate? I know there are two daily quests. But I need to know if there is a quest I have to do or which npc to talk to. I've tried to figure it out and google it but I can't find it. So any help would be great. Just looking to participate and have fun. I know oly is Friday Saturday and Sunday. But still confused. Thank you for help :)
