I just received my first leather order... what now?

So I just recently put in my order for some belly vegtan and it came in and I'm wondering... how do I process this stuff? Its SUPER dry and I don't wanna start working with it if there's something I need to do you know? I saw somewhere to soak it in water or do I apply some neatsfoot oil or something like that? I'm a completely novice leatherworker and I'd appreciate some advice!

Thank you all
