 OpenNetVM uses the [Meson][meson] build system to compile all components, including dpdk. From the `openNetVM` parent folder run the following to setup build:
 
 ```text

+This will take care of the Meson build setup, compilation, and installation of onvm shared libriaries.

 ### Running onvm_mgr
 
-After finishing build, from the build directory, you can run the `install` command to place the compiled executables in ther source directories.
