What is the safest, best way to introduce a new kitty to my bunny?

[Pandar ?? ?]

I currently have a 9 month old bunny and was planning on adopting an 11 month old cat from the pound. The cat seems really chill and is just a lovebug They said it was good with other cats, dogs, and small children, so I'm guessing he'll be okay with the bunny. (Hoping, at least!).

My bunny is the one I'm a bit more worried about. He's kind of a... prima-bunny. He can be extremely sweet sometimes; nuzzles me and falls asleep on me, and feels pretty comfortable in our home. However, he can get an attitude and apparantly is not very subject to change. We tried moving the furniture around because I was tired of the living room setting. He did not like this at all and let us know it by acting incredibly grumpy and nipping at us when we tried to love him. He was around cats and dogs before we adopted him though, and he got along with them really well.

I just want to avoid anything going wrong. I've never had to introduce animals before ._. It's nerve wracking!

Any advice would be greatly appreciated.
I was asking how to introduce them >_> like... tips on what to do.
