+///
+/// A [`Subscription`] is normally provided to some runtime, like a [`Command`],
+/// and it will generate events as long as the user keeps requesting it.
+///
+/// For instance, you can use a [`Subscription`] to listen to a WebSocket
+/// connection, keyboard presses, mouse events, time ticks, etc.
