+# Essential JS 2 QuickStart
+
+This project is a skeleton application used to create [Essential JS 2](https://www.syncfusion.com/products/essential-js2) web application.
+
+>This application uses the latest version of the [webpack-cli](https://webpack.js.org/api/cli/#commands). It requires node `v14.15.0` or higher.
+
+## Getting Started
+
+To get started you need to clone the `ej2-quickstart` repository and navigate to `ej2-quickstart` location.
+
+```
+git clone https://github.com/syncfusion/ej2-quickstart.git quickstart
+cd quickstart
+```
+
+## Installing
+
+We can get all the Essential JS 2 components in a single npm package [`ej2`](https://www.npmjs.com/package/@syncfusion/ej2).
+
+We already configure the required packages in the `package.json` file.
+
+You can run the below command to install all dependent packages related to this seed project.
+
+```
+npm install
+```
+
+## Testing
+
+This application is preconfigured with End-to-End testing and the test case is written in Jasmine.
+
+We run the test scripts with [Protractor](http://www.protractortest.org/#/) end-to-end test runner. The test case file can be found in the `e2e` folder.
+
+Protractor can interact with our web application and verify the test scripts.
+
+We have to install WebDriver and also need to ensure it is updated. Open a separate terminal and run the below npm script.
+
+```
+npm run update-webdriver
+```
+
+Open another terminal and run the below npm script. It will start web server to serve our application.
+
+```
+npm run serve
+```
+
+Once the web server is up and running, we can run the end-to-end tests using the below npm script
+
+```
+npm run test
+```
+
+> **Note:** Since Protractor is using the Selenium Standalone Server, the Java Development Kit (JDK) need to be installed in your local machine.
+
+If JDK is not installed in your local machine, you can download it from [here](http://www.oracle.com/technetwork/java/javase/downloads/index.html).
+
+## Running
+
+The application is configured with [webpack-dev-server](https://webpack.js.org/configuration/dev-server/#devserver), so it will serve the web application in your default browser.
+
+We have used [Webpack](https://github.com/webpack/webpack) for module loading.
+
+You can use the below npm script to run the web application.
+
+```
+npm run start
+```
+
+## Resources
+
+You can also refer the below resources to know more details about Essential JS 2 components.
