What goes into re-painting a bicycle?

Good day. I have an amazing bike that I really like but I do not like the way it looks. It is an aluminum frame and has a carbon fiber fork and seat post. I want to paint it. Obviously it would need to be disassembled and, I assume, sanded down….but is it realistic? Is that all there is to it? I really want to do this before the weather gets nice but I don’t want to get in over my head. Any helpful information or if anyone has ever repainted their bike before, would be great. Thanks!!
