Example:

:
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.14/angular.min.js"></script>
:
<div ng-app>
        <p><h4>Hello {{ sometext | uppercase }}!!! </h4></p>
        <p>Update Hello Text : <input type="text" ng-model="sometext" /></p>
</div>

Steps:
  • Load AngularJS library
  • AngularJS will initialize when the DOM content is loaded,
  • Looks for the ng-app directive and
  • It will start replacing all binding elements (e.g. curly braces, ng-bind).
