Code in API section of readme is outdated

I am making a project with this library, and there snippet in the readme seems to be outdated. I figured out how to use it from the test program.

Oh wow, neat! I haven't touched this code in agggggesssss tbh. I'm pleasantly surprised anyone finds it useful. Can you post your updated example here, @easrng ?

If I was doing this now I would set up automated testing. But this is really on my back-burner at the moment.
