 ### Information
 
+This challenge will teach you how to avoid unnecessary change detection cycles.
+
+Zone.js will trigger a change detection cycle each time a scroll event is dispatched. However we only want to show or hide a button at a specific scroll position. Therefore, we only want to refresh our application once.
+
+> You can vizualise how many times CD is triggered by installing the [Angular chrome devTool](https://chrome.google.com/webstore/detail/angular-devtools/ienfalfjdbdpebioblfackkekamfmbnh) and starting a new recording on the profiler tab.
+
 ### Statement
 
-### Step 1
+Your goal for this challenge is to avoid all those unnecessary change detection cycle and trigger a CD only when needed.
 
-### Step 2
+#### Constraint:
 
-### Constraints:
+You cannot opt-out of zone.js. If this code is part of a large project and you opt out of zone.js, you will break many things within your application.
