-# basic-keyboard
-Aspect which manages the keyboard focus and keydown handling for a component collective. This aspect ensures that its only the outermost aspect in a collective that is listening for keyboard events.
+The organization of these web component files is tuned for the component's
+inclusion in other projects via [Bower](http://bower.io). If you'd like to run
+this component's demo on your own machine, please see these
+[instructions](https://github.com/basic-web-components/components-dev/wiki/Running-Basic-Web-Component-demos).
