ember.js - using the ember manifest plugin

I want to have a manifest in my ember app, because I want to use it on mobile devices and have some offline capabilities.

I have found the plugin ember-cli-deploy-manifest: http://ift.tt/1WkYsMB It is well documented in the readme and looked promising.

But how do I use the plugin?

I have installed it using this command:

ember install ember-cli-deploy-manifest

I build my app using this command:

ember build -prod

No manifest is created. I am probably missing some simple step, but can't figure it out. How do I tell ember build to use the plugin?
