-This adds a message to the page to let the screen reader user know that the route has changed and regular page navigation can resume.
-It is similar to [https://github.com/ember-a11y/a11y-announcer](https://github.com/ember-a11y/a11y-announcer) but does not use aria-live.
+This addon does two things: 
+1. it adds a message to the page to let the screen reader user know that the route has changed and regular page navigation can resume (it is similar to [https://github.com/ember-a11y/a11y-announcer](https://github.com/ember-a11y/a11y-announcer) but does not use `aria-live`).
+2. It moves the focus to that message for the screen reader user- effectively resetting focus in Ember apps (which is the current, undesirable state for screen-reader users).
