+Example with an external board
+==============================
+
+This tests an external board implementation.
+The goal is to show using an external board that still needs to use the
+'RIOT/boards' directory.
+
+To allow automated testing by `murdock` this board is named 'native'.
+
+As it wants to extend native, which is not a common board, some hacks must be
+done as the 'board' module is implemented directly by the 'RIOT/boards/native'.
+
+If you are running an 'ubuntu-bionic' you could even compile the example in
+docker and run the test.
