+## System Requirements
+
+### Secure Context (HTTPS Deployment)
+
+When deploying your application / website for production, make sure to serve it via a secure HTTPS connection. This is required for two reasons:
+
+- Access to the camera video stream is only granted in a security context. Most browsers impose this restriction.
+- Dynamsoft License requires a secure context to work.
+
+> Some browsers like Chrome may grant access for `http://127.0.0.1` and `http://localhost` or even for pages opened directly from the local disk (`file:///...`). This can be helpful for temporary development and test.
+
+### Browser Compatibility
+
+The following table is a list of supported browsers based on the above requirements:
+
+| Browser Name |     Version      |
+| :----------: | :--------------: |
+|    Chrome    | v78+<sup>1</sup> |
+|   Firefox    | v68+<sup>1</sup> |
+|     Edge     |       v79+       |
+|    Safari    |      v14.5+      |
+
+<sup>1</sup> Devices running iOS need to be on iOS 14.5+ for camera video streaming to work in Chrome, Firefox or other apps using webviews.
+
+Apart from the browsers, the operating systems may impose some limitations of their own that could restrict the use of the SDK.
+

+
+## License
+
+Dynamsoft provides a complimentary trial license for the SDK. When you download the SDK package from the Dynamsoft website, after creating a Dynamsoft account, the following license will have a 30-day free trial:
+
+`DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9`
+
+>[!IMPORTANT]
+> Once your trial license expires, the SDK will throw an error and cease to function. You can visit the Dynamsoft Customer Portal (https://www.dynamsoft.com/customer/license/trialLicense?product=dbr&utm_source=installer&package=js) to view your trial license details. Additionally, it's possible to extend the trial period via the customer portal, allowing for a total trial duration of 60 days.
+

+
+## Quick Start
+
+Double-click `samples/hello-world.html` to instantly see a fully functional web application that scans a single barcode using your device's camera! You can also try `samples/read-an-image.html` to decode barcodes from an image file.
+
+>[!NOTE]
+> These samples load the SDK from a CDN so they can be opened directly as local files without a web server. An internet connection is required. To serve everything from the local `dist/` folder, see [Deploying to Your Server](#deploying-to-your-server).

 ## How to Run the Samples

+
+- `dist/` — All Barcode Reader JavaScript SDK resources (`.js`, `.wasm`, worker files, etc.)
+- `samples/` — Sample projects, including standalone examples (`hello-world.html`, `read-an-image.html`), framework integrations, and scenario demos
+- `LICENSE` — Dynamsoft license terms
+- `LEGAL.txt` — Third-party license notices

+>[!NOTE]
+> The included samples load from a CDN by default. To use the local `dist/` folder instead, a web server is required (the browser blocks local file fetches over `file:///`):
+> - **Standalone & scenario samples**: Switch to the commented-out `<script>` tag that points to the local `dist/` folder. No other changes are needed — the SDK infers resource paths from the script tag location.
+> - **Framework samples**: These use npm imports and explicitly set `engineResourcePaths` to a CDN URL. Update `engineResourcePaths.rootDirectory` to point to the local `dist/` folder.

 ## Sample Folders
 
-- `frameworks/` - This directory contains framework-specific examples demonstrating how to integrate the Dynamsoft Barcode Reader (JavaScript edition) into common web and hybrid frameworks. Each framework folder contains one or more runnable sub-examples (for example, scan-using-foundational-api and/or scan-using-rtu-api) showing practical integration patterns.
-- `scenarios/` - This directory contains focused scenario samples that show common real-world uses of the Dynamsoft Barcode Reader (JavaScript edition).
+The package includes two main sample directories:
+
+- **`frameworks/`** - Framework-specific examples showing how to integrate the Dynamsoft Barcode Reader into common web and hybrid frameworks. Each framework folder contains one or more runnable sub-examples (such as `scan-using-foundational-api` and/or `scan-using-rtu-api`). Included frameworks: Angular, Blazor, Capacitor, Electron, ES6, Native TypeScript, Next.js, Nuxt, PWA, React, RequireJS, Svelte, Vue, and WebView.
+
+- **`scenarios/`** - Focused scenario samples covering common real-world uses of the Dynamsoft Barcode Reader, including workflow patterns (Cart Builder, Scan and Search, Batch Inventory, etc.), barcode-type-specific scanning (QR Code, DataMatrix, 1D Retail/Industrial, etc.), and data parsing (Driver's License, VIN, GS1-AI).
+
+---
+
+## Choosing an API
+
+The SDK provides two approaches for integrating barcode scanning capabilities:
+
+### Ready-To-Use (RTU) API — BarcodeScanner
+
+The RTU API offers the quickest path to a working barcode scanner (**Recommended for most users**):
+
+- **One-line integration** – Launch a full scanner with a single API call
+- **Built-in UI** – Pre-designed viewfinder and scan region highlighting
+- **Simple configuration** – Customize behavior through intuitive config objects
+
+### Foundational APIs
+
+If you are looking for a fully customizable barcode decoding library with complete control over the scanning process and UI, you are welcome to use the Foundational APIs.
+
+---
+
+## Deploying to Your Server
+
+When you're ready to deploy your application to production, copy the `dist` folder to your server and reference it in your project:
+
+1. Copy the `dist` folder to your server
+2. Include the script and configure the SDK to load all resources locally:
+
+```html
+<!DOCTYPE html>
+<html>
+<head>
+    <title>Barcode Scanner</title>
+    <!-- Adjust the path based on where you host the dist folder -->
+    <script src="assets/dynamsoft-barcode-reader/dist/dbr.bundle.js"></script>
+</head>
+<body>
+    <script>
+        new Dynamsoft.BarcodeScanner({
+            license: "YOUR-LICENSE-KEY",
+            engineResourcePaths: {
+                rootDirectory: "assets/dynamsoft-barcode-reader/dist/"
+            }
+        }).launch().then(result => {
+            if (result.barcodeResults.length) {
+                alert(result.barcodeResults[0].text);
+            } else {
+                alert("No barcode found");
+            }
+        });
+    </script>
+</body>
+</html>
+```
+
+> When loading the SDK via a `<script>` tag, `engineResourcePaths` is optional — the SDK infers resource paths from the script tag location. It is required when using npm imports (e.g., in framework projects).
