How do I celebrate Passover?

My family is Jewish but we aren’t very religious. We’ve been trying to celebrate more Jewish holidays lately but aren’t quite sure on how to. We did our own take on Rosh Hashanah where we all got together and had dinner with the traditional foods and that was fun. And we’ve been celebrating hannukah for the last five years with my dad’s menorah from his childhood. What can we do to celebrate Passover? Thank you!
