+`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.
