Polytheism, please help meeee

I know a little about it but not much and it's going to be a predominant religion in the book I'm writing if anyone who knows a lot about this could just give me info or point me to websites that have correct information that would be great

Hi, what would you like to know? If you want some feedback on your own pantheon, I'd love to help! If you need help with some ideas, try searching up Greek, Roman, Egyptian, Indian, or Celtic mythology on Google; you'll get a lot of information.
