Before you create your first app, your environment must have the required components ready. These components ensure a smooth development, build, and test process. The default Ionic project folder is based on Cordova's. Therefore, you need the Ionic CLI to automatically add the correct platform (that is, iOS, Android, or Windows phone) and build the project. This will ensure all Cordova plugins are included properly. The tool has many options to run your app in the browser or simulator with live reload.
