 Sinatra is different from Rails. They're both frameworks for helping you to write web apps, but Sinatra contains fewer features and less magic.

 HTTP is used to send information between an application (like your Rails Girls app) and a browser.
 The basis of communication with HTTP is a request/response pair. Requests are sent by the browser to the server (e.g. your app) and the response is sent back from the server to your browser for a user to view.

 * Optionally there might be parameters on the end of the url, as key/value pairs, containing extra information about the request

 **Hint:** This global variable won't be around for very long - it will be reset to the empty array each time the server restarts.  Because we're using Sinatra's reloader, this will be every time you save your `app.rb` file.  Don't worry though, it will suit our purposes nicely.

 Now you'll need to get the information into that `$coffees` array when the request is received. When you fill in your form and click the submit button, remember that your information is put on the end of the URL, after the ?, to be sent back to the server.
 
  Sinatra grabs that information from the end of the URL and makes it available as a Hash called `params`. For example:
-

  {% highlight ruby %}
  params = {coffee = 'flat white', value ='2'}
 {% endhighlight %}
