var mainController = function($scope){

  $scope.message = Plunker;

};

and this is my HTML

<!DOCTYPE html>

<html ng-app>

    <head>

        <script [email protected] data-semver=1.6.1    src=https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.6.1/angular.js></script>

        <link rel=stylesheet href=style.css />

        <script src=script.js></script>

    </head>



    <body ng-controller=mainController>

        <h1>Hello {{ message }}</h1>

    </body>

</html>

To paraphrase http://www.w3schools.com/angular/angular_modules.asp

 <div ng-app=myApp ng-controller=mainController>

{{ firstName +   + lastName }}

</div>



<script>



var app = angular.module(myApp, []);



app.controller(mainController, function($scope) {

    $scope.firstName = John;

    $scope.lastName = Doe;

});



</script>

The important line is

    app.controller(mainController, function($scope)

which injects your controller into your app
