 ## Optimizations to Reduce Jank
 
-Considerations have been taken to reduce jank -- [please read more here](https://github.com/jscottsmith/parallax-controller#optimizations-to-reduce-jank) on how this is done
-
-### **PSA**
-
-Even with optimizations _scroll effects can cause jank_. It's also important to keep in mind that scroll effects are usually not critical to a users experience and sometimes can be annoying.
-
-If you use these components make sure you seriously consider the following:
-
-- Keep images small (do not use inappropriately high resolutions) and optimized (use appropriate compression)
-- Reduce the number of scroll effects on elements in view and on the page in total
-- Disable the use — or limit the amount — of scroll effects for users on mobile devices
-
-Follow the above and you should keep scrolling smooth and users happy.
