+/**
+ * @name ionicBoostrap
+ * @description
+ * `ionicBootstrap` allows you to bootstrap your entire application. Similar to Angualr's `bootstrap`, `ionicBootstrap`
+ * takes a root component in order to start the app. You can pass along any providers that you may want to inject into your
+ * app as an array for the second argument. You can also pass a config object as the third argument to configure your app's settings.
+ *
+ * @usage
+ * import {ionicBootstrap} from 'ionic-angular';
+ * import {Component} from '@angular/core';
+ *
+ * @Component({
+ *   templateUrl: 'build/app.html',
+ * })
+ *
+ * export class MyClass{}
+ *
+ * ionicBootstrap(MyClass, null, {tabbarPlacement: 'bottom'})
