 const int ANALOG_PIN = A0;

-##Methods for usage
+##Constructor arguments
+
+- `pin` - int, the pin to read (e.g. A0)
+- `sleepEnable` - boolean, sets whether sleep is enabled. Defaults to true. Enabling sleep will cause values to take less time to stop changing and potentially stop changing more abruptly, where as disabling sleep will cause values to ease into their correct position smoothly.
+- `snapMultiplier` - float, a value from 0 to 1 that controls the amount of easing. Defaults to 0.01. Increase this to lessen the amount of easing (such as 0.1) and make the responsive values more responsive, but doing so may cause more noise to seep through if sleep is not enabled.
+
+##Basic methods
 
 - `int getValue() // get the responsive value from last update`
 - `int getRawValue() // get the raw analogRead() value from last update`
 - `bool hasChanged() // returns true if the responsive value has changed during the last update`
 - `void update(); // updates the value by performing an analogRead() and calculating a responsive value based off it`
