 ## How it works
 The program checks the available frequency steps supported by your CPU and uses them to set the maximum frequency your cpufreq governor may choose for it to run at.
 
-Every second, the program reads the temperature of the CPU and two thresholds, a minimum and maximum temperature you provide it with, to set this maximum frequency.
+Every n ammount of seconds, set by the user at build time, the program reads the temperature of the CPU and two thresholds, a minimum and maximum temperature you provide it with, to set this maximum frequency.
 
 Any time the temperature hits the upper threshold, the maximum frequency will be lowered by one step, until the temperature is below the threshold or the minimum step is reached.
