Melodica/ Wind Piano?

I was just wondering if any users know how to play a melodica. I think its a pretty uncommon instrument, its also called a wind piano. I have an alto melodica.

I know a bit about them and I’ve been experimenting with it. Its played like a piano but, you blow into it as well. Sadly I don’t know how to play a piano, just the alto saxophone.

Anyway, just any tips and advice pianists, melodica players, or multi-instrumentalists could give me would be much appreciated!
