title: How to install ngSanitize?
body: <p>I'm trying to use ngSanitize so that I can inject html content ( external) into my app. However I got stuck at the ngSanitize installation. If I add it into my app module it stops working . Should I download this from somewhere ? Angularjs docs don't say anything.</p>
  
  <pre><code>var crmApp = angular.module('crmApp', [
    'ngRoute',
    'crmControllers',
    'ui.bootstrap',
    'ngSanitize',
  ]);
  </code></pre>
