How do I become more jewish?

I’ve never been much of a religious person. I went to sunday school and a jewish preschool but that’s about it, it was never forced on me. My family celebrates hanukkah (christmas too just not the religious aspect) and used to celebrate Shabbat. I’ve never been to temple I don’t think.

I really don’t know much when it comes to judaism and I don’t know where to start. I would like it to be a thing with my family but we really just claim we’re jewish and that’s it. I know it’s in our blood from 23&me testing.
