 Add the following lines to your AppDelegate or Controller:
 
 ```objc

-    SEGAnalyticsConfiguration *config =

 ```
 
 Now you can use Segment as you are used to, e.g.:
 
 ```objc
-    [[SEGAnalytics sharedAnalytics] track:@" ... " properties:@{ ... }];
+[[SEGAnalytics sharedAnalytics] track:@" ... "];
 ```
 
 In addition to that you can also use the advanced features of Leanplum, e.g.:
 
 ```objc
-    [Leanplum onVariablesChanged: ... ]
+[Leanplum onVariablesChanged:^{
+    ...
+}];
 ```
