-        export RTE_SDK=/path/to/rte_sdk
-        cd ${RTE_SDK}/examples/ipv4_multicast

-#.  Set the target (a default target is used if not specified). For example:
-
-    .. code-block:: console
-
-        export RTE_TARGET=x86_64-native-linuxapp-gcc
-
-See the *DPDK Getting Started Guide* for possible RTE_TARGET values.

-    The compiled application is written to the build subdirectory.
-    To have the application written to a different location,
-    the O=/path/to/build/directory option may be specified in the make command.
+The application is located in the ``ipv4_multicast`` sub-directory.
