document Shelly vs Shelly.Lifted vs Shelly.Pipe

[juhp]

I am a bit unclear about the difference between Shelly and Shelly.Lifted particularly, though also Shelly.Piped (supports piping with >>=?).

Is it possible to add a sentence or two to the docs explaining the distinction and when you would use one or the other? An example or two would be helpful too.

Thanks for Shelly!
