So what did Zarathrustra actually say

I recently bought this book on a sale, it was the only one by Nietzsche.
I've heard that before reading this one you should read basically everything else from mr Ubermensch if you're just starting out with nihilism.
Is this true? I wouldn't want to start reading it only to leave it because I need to understand the other stuff first.
I studied most of what stoicism had to offer, if that helps.
