            <h1>Welcome to Play</h1>

            <p>
                Congratulations, you’ve just created a new Play application. This page will help you with the next few steps.
            </p>

            <blockquote>
                <p>
                    You’re using Play @version
                </p>
            </blockquote>

            <h2>Why do you see this page?</h2>

            <p>
                The <code>conf/routes</code> file defines a route that tells Play to invoke the <code>HomeController.index</code> action
                whenever a browser requests the <code>/</code> URI using the GET method:
            </p>

            <pre><code># Home page
GET     /               controllers.HomeController.index</code></pre>


            <p>
                Play has invoked the <code>controllers.HomeController.index</code> method:
            </p>

            <pre><code>public static Result index() {
    return ok(index.render("Your new application is ready."));
}</code></pre>

            <p>
                An action method handles the incoming HTTP request, and returns the HTTP result to send back to the web client.
                Here we send a <code>200 OK</code> response, using a template to fill its content.
            </p>

            <p>
                The template is defined in the <code>app/views/index.scala.html</code> file and compiled as a standard Java class.
            </p>

            <pre><code>@@(message: String)

  @@main("Welcome to Play") {

  @@play20.welcome(message, style = "Java")

}</code></pre>

            <p>
                The first line of the template defines the function signature. Here it just takes a single <code>String</code> parameter.
                Then this template calls another function defined in <code>app/views/main.scala.html</code> which displays the HTML layout, and another
                function that displays this welcome message. You can freely add any HTML fragment mixed with Scala code in this file.
            </p>

            <blockquote>
                <p>
                    <strong>Note</strong> that Scala is fully compatible with Java, so if you don’t know Scala don’t panic, a Scala statement is very similar to a Java one.
                </p>

            <h2>Async Controller</h2>

            Now that you've seen how Play renders a page, take a look at <code>AsyncController.java</code>, which shows how to do asynchronous programming when handling a request.  The code is almost exactly the same as <code>HomeController.java</code>, but instead of returning <code>Result</code>, the action returns <code>CompletionStage&lt;Result&gt;</code> to Play.  When the execution completes, Play can use a thread to render the result without blocking the thread in the mean time.

            </p>

            <h2>Count Controller</h2>

            <p>
                Both the HomeController and AsyncController are very simple, and typically controllers present the results of the interaction of several services.  As an example, see the <code>CountController</code>, which shows how to inject a component into a controller and use the component when handling requests.  The count controller increments every time you click on it, so keep clicking to see the numbers go up.
