Mixed documentation for .subscribe()

[heavy-matill]

To subscribe for events the documentation in README.md differs from implementation
README.md suggests:
// Register callback MusicControls.subscribe(events);

index.d.ts documents @usage as:
this.musicControls.subscribe().subscribe(action => {...});

The latter does work, so it should be fixed in README.md. However I would rather like the implementation to switch from .subscribe().subscribe(...) to .subscribe(...).

Thanks I'll review the docs, it's been a while since I looked at them properly.
