Baby registry

So I started a registry on Amazon and I have NO idea if I'm doing it right! 😂 do you just put whatever you want on there so people have options to pick from or specific things? I moved across the country since my boyfriend is in the Navy and my mom is doing like an online baby shower raffle thing so I figure Amazon would work the best for my family back home. Seeing as it's my first child, I have no idea what I'm doing with anything 😅 any and all help or advice is super appreciated!!
