laravel subscribable rss feed service

I am using rss feed service with laravel 5.3

I have implemented service in controller as below:

public function index()
    {
        $news = News::with('user')->orderBy('created_at', 'desc')->take(4)->get();

        $feed = App::make('feed');
//        $feed->id = 'My blog';
//        $feed->title = 'My blog';
//        $feed->description = 'This is my blog about this';
//        // $feed->logo = asset('img/logo.png'); //optional
//        $feed->link = url('feed');
//        $feed->setDateFormat('datetime'); // 'datetime', 'timestamp' or 'carbon'
//        $feed->pubdate = $news[0]->created_at;
//        $feed->lang = 'en';
//        $feed->setShortening(true); // true or false
//        $feed->setTextLimit(100); // maximum length of description text

        foreach ($news as $post)
        {
            // set item's title, author, url, pubdate, description and content
            $feed->add($post->title, $post->user->name, url('posts/' . $post->id), $post->created_at, $post->description, $post->description,['user_id'=>$post->id, 'photo'=>$post->photo]);
        }

        $news = $feed->render('rss'); // or atom
        return view('home',compact(['news']));
    }

and iterate feed items in blade view:

<link rel="alternate" type="application/rss+xml" title="My blog" href="" />
    @foreach($news->original->items as $new)
                            <div class="blog-item">
                                <img class="img-responsive img-blog" src="/images/newsphotos/" width="100%" alt="" />
                                <div class="blog-content">
                                    <a href="blog-item.html"><h3></h3></a>
                                    <div class="entry-meta">
                                        <span><i class="icon-user"></i> <a href="#"></a></span>
                                        <span><i class="icon-folder-close"></i> <a href="#">Bootstrap</a></span>
                                        <span><i class="icon-calendar"></i> </span>
                                    </div>
                                    <p>
                                        
                                    </p>
                                    <a class="btn btn-default" href="">Read More <i class="icon-angle-right"></i></a>
                                </div>
                            </div><!--/.blog-item-->
                        @endforeach

It looks fine, the thing is I search on the net browsers can recognize ress services and let users "subscribe" but my browsers all unawera of this information..

How can I make this subscribable by browsers ?
