-The `route-action` helper allows you to bubble closure actions, which will delegate it to the currently active route hierarchy per the bubbling rules explained under `actions`. Like closure actions, `route-action` will also have a return value.
+The `route-action` helper allows you to call actions from routes. Like closure actions, `route-action` will also have a return value.
 
-However, returning `true` in an action will **not** preserve bubbling semantics. In case you would like that behavior, you should use ordinary string actions instead.
+Route actions do not bubble. In case you would like that behavior, you should use ordinary string actions instead.
 
 ## Usage
 
-For example, this route template tells the component to lookup the `updateFoo` action on the route when its internal `clicked` property is invoked, and curries the function call with 2 arguments.
