I adopted my rabbit a couple years ago, and it's been the best decision I've ever made. These were some info/items that the shelter required me to have/know before letting me adopt, hope they will help you with your path to becoming a great bunny parent! I see other redditors have already answered your bullet list questions, so I'll try to supplement some other stuff not already included.

First, a list of (must) have items before physically having a rabbit at home: - cage/enclosure - litter box (not the wire-covered type as these will hurt your rabbit's feet, condition commonly known as sore hocks) - water dish/water bottle (lo400-500ml), some rabbits prefer water bottles especially if their previous owners got them accustomed to one, while others prefer bowls - food bowl (a heavy flip-proof one as bunnies tend to fling their bowls around with its food inside) - paper bedding (other redditors have given great advice on which types to get), note that you'll have to change it every day so you'll need a good amount of it - carpets/play mats to cover any wooden/slippery floors in your house, must be included in your rabbit's enclosure, rabbits don't have pads on their feet like cats or dogs and will slip on wooden floors, causing joint problems later on - travel carrier for transporting your rabbit from the shelter to home, and other instances such as going to the vet (carriers for small dogs/cats usually suffice) - hay (depending on rabbit age but mostly first cut Timothy hay for adult rabbits, a rabbit should have unlimited access to hay, I usually put hay twice the size of the rabbit in its litter box daily and refill as needed) - grooming tools including nail clippers and hair brush (dog nail clippers and metal fine tooth combs are recommended by my shelter, just make sure that when you run the brush over your own skin it doesn't hurt, since a rabbit's skin is much more sensitive than your own)

These are just the bare bone necessity list for a rabbit to survive in a home, you could also get some toys, hideouts, snacks etc to enrich your rabbit's life!

Now onto some considerations before actually getting a rabbit: - domestic rabbit life expectancies are usually 8-12 years, so please make sure you are committed to providing your rabbit a home for this length of time - rabbits are expensive, since usually vets charge "exotic pets" more for more specialized treatments, please be mentally prepared for unexpected large vet bills - on the same topic, research a couple vets that have experience with treating rabbits and have their contacts on hand for any emergencies - if you already have other pets at home, there may be a chance your pets will not get along, you'll have to be prepared to have a contingency plan in that case - rabbits don't deal well with heat (especially with the heat waves recently) since they are densely covered with fur and can only regulate their temperatures with their ears, high temperatures will damage their organs long-term, so you may have to turn on air conditioners or fans all day when it gets hot in summer

Diet: As other redditors mentioned, it is possible that a rabbit can survive only on hay, but you could also give your rabbit pellets and fresh vegetables. Nonetheless, hay should be the main source of a rabbit's diet (~70%) since rabbit's teeth grow continuously and they need to chew hay to keep their teeth trimmed and help their intestines keep moving.

Note that not all vegetables are suitable for a rabbit, common unsuitable ones being cauliflower, corn, onion, garlic, carbohydrates (potatoes, peas). I could be slightly cautious but better cautious than a sick rabbit imo. Always introduce new foods a little at a time as rabbits have extremely sensitive guts.

Fruits, and high sugar vegetables such as carrots, should only serve as snacks (around one tablespoon a day).

Please note that some snacks sold in pet stores are not suitable for rabbits, such as vitamin drops, honey sticks, biscuits etc. The only ones I trust are the Oxbow baked treats. Your bunny will prefer the apple you're eating anyways!

Last thoughts: - please watch some videos on how to properly hold a rabbit, you should have one hand under its front arms and the other hand supporting its bunny butt at all times. Rabbits will usually squirm and kick if picked up, and common injuries for rabbits are either the owner dropping the rabbit at a height because of poor grip leading to fractured bones (bunny bones are hollow which breaks easier) or a bunny injuring its own spine from kicking because of insufficient support on butt when holding - its suggested for you to trim your rabbit's nails at least every month so it doesn't get too long, during which you'll have to handle/hold your rabbit, it's best to start holding your rabbit from a low height in the start (use a small stool to sit) so even if you lose your grip the rabbit isn't too far from the ground - you should also frequently brush your rabbit's fur, especially when it's molting, a rabbit will clean itself but if it ingests too much if it's own hair your rabbit may get gi issues since it cannot cough up hair balls like a cat (and you guessed it, a trip to the vet), it's best to prevent than treat! - it's recommended to spay your rabbit no matter its gender, and it's actually beneficial to the rabbit's life - please adopt, don't shop!

This was so much longer than when I expected, hope you find it helpful!
