+start a journey in your application by using the `startJourney` method and passing the ID
+of the journey. 
 
 ```javascript
-const journey = new Shepherd.Tour({
-  id: 'custom-123',
-  defaultStepOptions: {
-    cancelIcon: {
-      enabled: true
-    },
-    classes: 'my-custom-class'
-  },
-  useModalOverlay: true
-});
+Shepherd.`startJourney`('custom-UUID');
 ```
 
-Then you just need to add steps to the journey instance and trigger the start method to begin. Shepherd Pro will take care of the rest and capture events in the portal.
