+Summary
+-------
+
+The primary use of the library is to easily interface with a MAX6675 chip via it's SPI interface.  Use the following code to initialize the library.  V2 also greatly improves performance and timing of the chip for more accurate reads.  Thanks Ed!
+
+	MAX6675 temp0(CS,SO,SCK,units);
+
+Variables:	
+
+*	CS is chip select pin of chip
+*	SO is data out of the chip
+*	SCK is the clock pin of the chip
+*	units is one of the following:
+	*	0 = raw 0-4095 value
+	*	1 = temp in ˚C
+	*	2 = temp in ˚F
+	
+Following this you can use the _read_temp()_ function to return the temperature as a float.
+
+	temperature = temp0.read_temp();
