Where does the ad code go?

Thank you very much for building this. There must be something too obvious to bother saying that I’m missing.

After I’ve input the pub-id in the settings and in the user window, where does the ad code go? Wherever it is, do I simply put in my own ad code or do I have to modify it in some way?
