+## Enable One-Wire Interface
+
+One-wire is a single-wire communication bus typically used to connect sensors
+to the RaspberryPi. The Raspberry Pi supports one-wire on any GPIO pin, but
+the default is GPIO 4. To enable the one-wire interface explicitly set it in
+`local.conf`

+    ENABLE_W1 = "1"
+
+Once discovery is complete you can list the devices that your Raspberry Pi has
+discovered via all 1-Wire busses check the interface with this command
+
+`ls /sys/bus/w1/devices/`
