For Plunker, just use the <a href="http://plnkr.co/edit/?p=preview">starter template</a> to get going. If you're

This example serves the Angular library from <a href="http://code.angularjs.org">code.angularjs.org</a>. This is
fine for examples, but you'd want to serve it yourself or use a CDN for real deployment.

h2#section-transpile Great job! We'll have the next steps out soon. h2#section-set-up-the-starting-component Set up the starting component
p.
In <code>main.js</code>, create a class called <code>AppComponent</code>, configure it to bind to the
<code>&lt;my-app&gt;</code> element in <code>index.html</code>, and call Angular's <code>bootstrap()</code> to kick
it all off like this:
pre.prettyprint.lang-javascript
code.
//ES5
function AppComponent() {}
AppComponent.annotations = [
new angular.Component({
selector: 'my-app'
}),
new angular.View({
template: '&lt;h1&gt;My first Angular 2 App&lt;/h1&gt;'
})
];
document.addEventListener('DOMContentLoaded', function() {
angular.bootstrap(AppComponent);
});
pre.prettyprint.lang-typescript
code.
//TypeScript
import {Component, View, bootstrap} from 'angular2/angular2';
@Component({
selector: 'my-app'
})
@View({
template: '&lt;h1&gt;My first Angular 2 App&lt;/h1&gt;'
})
class AppComponent {
}
bootstrap(AppComponent);

Open <code>index.html</code> through your web server or hit the <strong>Run</strong> button if using Plunker and
you should see:

h2#section-explanations Explanations
p This basic Angular app contains the structure for any app you'll build.
p.
You can think of Angular apps as a tree of components. This root component we've been talking about acts as the top
level container for the rest of your application. You've named this one <code>AppComponent</code>, but there's
nothing special about the name and you can use whatever makes sense to you.
p.
The root component's job is to give a location in the <code>index.html</code> file where your application will
render through it's element, in this case <code>&lt;my-app&gt;</code>. There is also nothing special about this
element name and you can pick it as you like.
p.
The root component loads the initial template for the application that will load other components to perform
whatever functions your application needs - menu bars, views, forms, etc. We'll walk through examples of all of
these in the following pages.
p Exciting! Not excited yet? Let's move on to <a href="displaying-data.html">Displaying Data</a>.
