title: Unclear instructions to install Laravel Telescope in dev only
body: <p>I was trying to install <a href="https://github.com/laravel/telescope" rel="nofollow noreferrer">Laravel Telescope</a> in my local dev environment. According to the <a href="https://laravel.com/docs/5.7/telescope" rel="nofollow noreferrer">docs</a>, to install it in specific environments</p>
  
  <blockquote>
    <p>you should remove the <code>TelescopeServiceProvider</code> service provider registration from your <code>app</code> configuration file. Instead, manually register the service provider in the <code>register</code> method of your <code>AppServiceProvider</code>:</p>
  </blockquote>
  
  <p>But I didn't find Telescope being registered in my <code>app</code> configuration file. I have no clue where the registration takes place. I'm using a fresh Laravel install, and the <code>/telescope</code> route works.</p>
  
  <p>Why is it not registered in <code>config/app.php</code> as mentioned in the docs?</p>
