Now that Chrome is helping you with testing and packaging your application, all that's left to do is to augment your existing Angular application to support the Chrome App APIs and structure.

This file is called manifest.json.

The manifest.json file is a simple JSON file that contains information used by Chrome to manifest your Angular Chrome App. The required keys that Chrome needs to successfully display your app include manifest_version, name, and version.

  "version" : "0.1",
  "manifest_version" : 2
}
