+System Requirements
+-------------------
+
+The DPDK and its applications require the GNU make system (gmake)
+to build on FreeBSD. Optionally, gcc may also be used in place of clang
+to build the DPDK, in which case it too must be installed prior to
+compiling the DPDK. The installation of these tools is covered in this

+
+Compiling the DPDK requires the FreeBSD kernel sources, which should be
+included during the installation of FreeBSD on the development platform.
+The DPDK also requires the use of FreeBSD ports to compile and function.
+
+To use the FreeBSD ports system, it is required to update and extract the FreeBSD
