-`core-signals` provides basic publish-subscribe functionality.
-
-Note: avoid using `core-signals` whenever you can use
-a controller (parent element) to mediate communication
-instead.
-
-To send a signal, fire a custom event of type `core-signal`, with
-a detail object containing `name` and `data` fields.
-
-    this.fire('core-signal', {name: 'hello', data: null});
-    
-To receive a signal, listen for `core-signal-<name>` event on a 
-`core-signal` element.
-
-  <core-signal on-core-signal-hello="{{helloSignal}}">
-
-You can fire a signal event from anywhere, and all 
-`core-signal` elements will receive the event, regardless
-of where they are in DOM.
