+This sample demonstrates how to use the library in an Angular application in the most basic manner. [Angular CLI](https://github.com/angular/angular-cli) v11.2.4 is used to generate this sample project.
 
 As mentioned in the user guide, when working with Angular aplications, it is recommended to use the `dynamsoft-javascript-barcode` npm package. The library is then set up as its own component, in this case defined in `barcode-scanner`.
 
-The majority of the `DBR` (short for Dynamsoft Barcode Reader) operations are grouped in the `barcode-scanner` folder. Since we are using the npm package, the engine files are not in the same location as the main library file, `dbr.ts`. Therefore, the `engineResourcePath` must be defined so that the library knows where to find the engine files.

 The barcode scanner component is defined in the `components` folder. `BarcodeScanner.js` is the most basic implementation of the library as a React component. The `BarcodeScanner` component is then used in the parent component, `HelloWorld`.

+The Vue implementation of the Hello World sample is very similar to the React and Angular implementations. Of course, this implementation will be based on the npm package `dynamsoft-javascript-barcode`.

+# UI Customization Sample Set
+
+In this sample set, we will focus on the library's flexible UI that allows developers to create the look and feel for their web application that they desire. To learn more about UI customization, please refer to its corresponding [section](https://github.com/Dynamsoft/javascript-barcode#233-customize-the-ui) in the user guide.
+
+Let's begin by breaking down each of the samples in this set
+
+### Read Barcodes via Video and Display Results
+
+In this sample, we perform simple tweak of the default UI to include a couple of `span` elements that will display the barcode text and barcode format as they are detected via video. Our basic 'Hello World' samples displayed the results in the console or via an alert box, so this sample will offer a more user-friendly way of showing the results as they are found.
+
+In the `onFrameRead` event function, a pair of `span` elements are created for each found barcode. The `span` elements are then populated with the barcode text and the barcode format. Afterwards, the scanner UI (via `getUIElement`) is appended to the newly created `span` elements to complete this custom UI.
