 # How It Works
 
-The `build/packager.js` tool is a node.js script that concatenates and
-wraps various .js files with a RequireJS-compatible module syntax in this
-project together to generate cordova.js files that are compatible
-to the various supported platforms. Check that script out to figure out
-how and in what order the various files are concatenated together.
-
-We end up with a script file that has a ton of `define` calls, wrapping
-each Cordova API or object into its own module. Next, the Cordova bridge is initialized with
the
-help of `lib/bootstrap.js`. This file attaches the `_self.boot` function
-once the `channel.onNativeReady` event is fired - which should be fired
-from the native side (native should call `require('cordova/channel).onNativeReady.fire()`).
-Finally, the `boot` method is where the magic happens.  First, it grabs
-the common platform definition (as defined under
-`lib/platform/common.js`) and injects all the objects defined in there
-onto `window` and other global namespaces. Next, it grabs all of the platform-specific object
-definitions (as defined under `lib/platform/<platform>.js`) and
-overrides those onto `window`. Finally, it calls the platform-specific
-`initialize` function (located in the platform definition). At this
-point, Cordova is fully initialized and ready to roll, however, before
-the `deviceready` event is fired, we still wait for the
-`DOMContentLoaded` event to fire to make sure the page has loaded
-properly.
+The `build/packager.js` tool is a node.js script that concatenates all of the core Cordova
plugins in this repository into a `cordova.<platform>.js` file under the `pkg/` folder.
It also wraps the plugins with a RequireJS-compatible module syntax that works in both browser
and node environments. We end up with a cordova.js file that wraps each Cordova plugin into
its own module.
+
+Cordova defines a `channel` module under `lib/channel.js`, which is a publish/subscribe implementation
that the project uses for event management.
+
+The Cordova native-to-webview bridge is initialized in `lib/bootstrap.js`. This file attaches
the `boot` function to the `channel.onNativeReady` event - fired by native with a call to:
+
+    cordova.require('cordova/channel).onNativeReady.fire()
+
+The `boot` method does all the work.  First, it grabs the common platform definition (under
`lib/platform/common.js`) and injects all of the objects defined there onto `window` and other
global namespaces. Next, it grabs all of the platform-specific object definitions (as defined
under `lib/platform/<platform>.js`) and overrides those onto `window`. Finally, it calls
the platform-specific `initialize` function (located in the platform definition). At this
point, Cordova is fully initialized and ready to roll. Last thing we do is wait for the `DOMContentLoaded`
event to fire to make sure the page has loaded properly. Once that is done, Cordova fires
the `deviceready` event where you can safely attach functions that consume the Cordova APIs.
 
 # Testing

 Final testing should always be done with the [Mobile Spec test application](https://github.com/apache/incubator-cordova-mobile-spec).
