+This library is written to manage Xadow. It includes functions to:
 
-* user led
-* charge state read
-* battery voltage read
-* sleep mode operation
+* control the LEDs 
+* read the charge state
+* read the battery voltage
+* put the xadow to sleep
+
+Also see the examples directory for:
+
+* reading the barometer
+* vibrating the vibrator
+* reading the accelerometer
+* reading and setting the real-time-clock
 
 FUNCTION
 -------------------------------------------------------------------------------------------------------------------
-you can use the folowing function, it's useful in some way.
+It contains the following functions:
 
 ### Initialization
 	void init();
 
-### Get Voltage of battery
+### Get the voltage of the battery
 	float getBatVol();
 
-### Get Charge State
+### Get the charge state
 	unsigned char getChrgState(); 
 
-it'll return the folowing value:
+getChrgState() will return one of the following values:
 
 	#define NOCHARGE            0
 	#define CHARGING            1
 	#define CHARGDONE           2
 
-### User Led
-there'are two user led that you can use, a green one and a read one.
+### User LED
+there'are two user LEDs that you can use, a green one and a red one.
 
-	void greenLed(unsigned char state);             // green Led drive
-	void redLed(unsigned char state);               // red led drive
+	void greenLed(unsigned char state);             // green LED drive
+	void redLed(unsigned char state);               // red LED drive
 
-about the input value, you can use:
+To control the LED state, you use:
 
-	#define LEDON               1               	// led on
-	#define LEDOFF              2               	// led off
-	#define LEDCHG              3               	// change led state		
+	#define LEDON               1               	// turn the LED on
+	#define LEDOFF              2               	// turn the LED off
+	#define LEDCHG              3               	// toggle the LED state
 
-### Power Manage
-of curse, sometimes you want your xadow goto sleep to save some power, then you can use this function:
+### Power Management
+Sometimes you may want to put your xadow to sleep to save power. Use:
 
-	void pwrDown(unsigned long tSleep);             // power down, tSleep ms
+	void pwrDown(unsigned long tSleep);             // power down, tSleep milliSeconds to sleep for
 
-it'll let your xadow goto sleep for sSleep ms, then it'll wake, you shourld use the folowing function to awake it:
+It will put your xadow to sleep for sSleep ms, then it will wake. You should use the following function to wake it up:
 
 	void wakeUp();                                  // wake up
