 ## Hello World with RequireJS
 
 This sample shows how to use the SDK in a web page based on RequireJS.
 
-Let's quickly break down the methods used in order:
-
-* `license`: This property specifies a license key.
-* `createInstance()`: This method creates a `BarcodeScanner` object. This object can read barcodes directly from a video input with the help of its interactive UI (hidden by default) and the MediaDevices interface.
-* `onFrameRead`: This event is triggered every time the SDK finishes scanning a video frame. The `results` object contains all the barcode results that the SDK have found on this frame. In this example, we print the results to the browser console.
-* `onUniqueRead`: This event is triggered when the SDK finds a new barcode, which is unique among multiple frames. `txt` holds the barcode text value while `result` is an object that holds details of the barcode. In this example, an alert will be displayed on unique reads.
-* `show()`: This method brings up the built-in UI of the `BarcodeScanner` object and starts scanning
-
-Actually, it is not necessary to define both onFrameRead and onUniqueRead in the code. onUniqueRead is more commonly used because it is triggered only when a new barcode is detected, rather than on every frame.

 ## Hello World with ES6
