 # How is container CPU calculated ?
 Kondense resize each container CPU every second with the following steps.
 
-## 1. Calculate average CPU usage of the container.
+## 1. Calculate container average CPU usage
 Kondense calculate the average CPU usage over the last `INTERVAL` seconds. By default, `INTERVAL` is 10 seconds.
 
 ### 2. Calculate new CPU
-To calculate the new container CPU, we need the `TARGET_AVG`. By default, `TARGET_AVG` is 0.8 so 80%.
