+**node-fetch** : Fetching images for logo and background\
+**sharp** : Converting images between different formats ( SVG, JPEG, PNG)\
+**probe-image-size**: Retrive meta data of images.
+
+## Run Locally
+
+Once the packages are installed we can start generating QR code locally.
+Open the `index.test.ts` file and edit the QR attributes ( config ) as needed.
+
+Sample config 
+
+```bash
+  const config = {
+    text: "Sample Data",
+    logoBackground: true,
+    backgroundColor: "#ffffff",
+    canvasType: CanvasType.SVG,
+    dataPattern: DataPattern.SQUARE,
+    dotScale: 1,
+    colorDark: "#000000",
+    colorLight : '#00FFFF',
+    eyeBallShape: EyeBallShape.SQUARE,
+    eyeFrameShape: EyeFrameShape.SQUARE,
+    eyeFrameColor : '#000000',
+    eyeBallColor : '#000000',
+    frameStyle: QRCodeFrame.NONE,
+    frameText: "",
+    frameColor: "#724DDB",
+    frameTextColor: "#FFFFFF",
+    gradientType: GradientType.NONE,
+    logoScale: 0.27,
+    backgroundImage :'https://s3.amazonaws.com/beaconstac-content-qa/5118/890b88c1e2c2406cafa6f6eec5240287',
+    logoImage : 'https://images.freeimages.com/images/previews/ac9/railway-hdr-1361893.jpg',
+    size: 1024,
+    margin: 80,
+    correctLevel: QRErrorCorrectLevel.H,
+    logoMargin : 0,
+    isVCard : false
+
+};
+```
+
+Once you have edited the config according to your requirement, run the following command
+
+```bash
+  npm run testMain
+```
+
+This will generate 3 files inside the same folder as `index.test.ts` ( `mobstac-awesome-qr/src/test/index.test.ts`). The files generated will be `test.svg`, `test.jpeg`, `test.png`. These files contain the QR code generated with the given config.
+
+
+
+
