+## Building Examples
+
+To build each of the examples cd to the subdirectory of the example
+and type 'make'
+
+You may need to install the following before building:
+```
+  sudo pip install empy pydronecan pexpect
+```
+
+## Running Examples
+
+Before you run the examples you need to start socketcan on Linux. See
+the setup_socketcan.sh script in this directory for starting socketcan
+
+After socketcan is setup you can run an example like this:
+```
+ ./esc_node vcan0
+```
+Then connect to vcan0 with the DroneCAN GUI Tool. For the esc_node and
+servo_node you will need a dynamic node allocation server, which you
+can start within the DroneCAN GUI tool using the rocket icon in the
+bottom right corner
