+If you wish to work on the SPI implementation, simply clone the repository
+"serbus", a small C stack available at `github.com/mgreiff/serbus` into your
+julia package directory (for example "~/.julia/v0.6"). Then, in the
+LabConnections package on the host computer, run `flash_BB.sh` in the "/utils"
+directory transferring both LabCOnnections and serbus to the BB.
+
+On the BB, run
+
+  cp /home/debian/juliapackages/serbus/bb_spi.sh /home/debian
+
+and then execute
+  
+  ./bb_spi.sh
+
+in the `/home/debian` directory to run the SPI example with the ADC from SPI0.
