       want to try out Angular while it is in alpha.
   
   // STEP 1 - Create a project ##########################
  
positive.code: 
    p.
      Create two files, <code>index.html</code> and
      <code>app.es6</code>, both at the root of the project:
  
    pre.prettyprint
      code.
        touch index.html
        touch app.es6
  
    .alert.is-helpful.
      The <code>.es6</code> extension signifies that the file uses ES6 syntax. If your editor doesn't
      support syntax highlighting for .es6, use .js.
  
    p Inside of <code>app.es6</code>, import the required modules from Angular:
  
    pre.prettyprint.linenums
      code import {Component, Template, bootstrap} from 'angular2/angular2';
  
    p.
      The above import statement uses ES6 module syntax to import three modules from Angular.
      These modules load at runtime.
  
  
  // STEP 4 - Create a component ##########################
  
negative.code:     that has an HTML tag named <strong><code>&lt;my-app&gt;</code></strong>.
  
    p.
      A component consists of two parts, the <strong>component controller</strong>
      which is an ES6 class, and the <strong>decorators</strong> which tell Angular
      how to place the component into the page.
  
    pre.prettyprint.linenums
      code.
