Thinking about picking up volleyball

[KingTripleJump]

I am already a basketball official and I am thinking about doing volleyball next year. Is it hard to pick up? I know a little volleyball but not a whole lot.

Also, I don't want to be one of those officials who doesn't know a thing about it but is still doing it anyway. So if it is easy to learn, then I will pick it up. If not, then I will leave it be.
