+SPI.h library by default only support Master mode, the SPI.begin() will automatically set slave select (ss) pin to HIGH whether you have pinMode(ss, OUTPUT) in your setup() code or not and set the Arduino as an SPI master.
+As the SPI library does not contain the functionality for slave mode, in order to use Arduino as a Slave, you will need to do some customised setup, mainly on
+  - setting MISO as OUTPUT for slave to send data
+  - enable slave mode by setting the SPCR register
+  - enable interrupt when data is received.
