 You can also configure individual client instances as follows:

 keen-gem can be used with [em-synchrony](https://github.com/igrigorik/em-synchrony).
 If you call `publish_async` and `EM::Synchrony` is defined the method will return the response

 This is useful for situations like tracking email opens using [image beacons](http://en.wikipedia.org/wiki/Web_bug).
 
 In this situation, the JSON event data is passed by encoding it base-64 and adding it as a request parameter called `data`.
 The `beacon_url` method found on the `Keen::Client` does this for you. Here's an example:
 
-    keen = Keen::Client.new(:project_id => '12345',
-                            :api_key => 'abcde')
+    keen = Keen::Client.new(:project_id => '12345', :api_key => 'abcde')
 
     keen.beacon_url("sign_ups", :recipient => "[e-mail]")

 To track email opens, simply add an image to your email template that points to this URL.
