+MoonGen
+-------
+
+Installation
+~~~~~~~~~~~~
+
+MoonGen architecture overview and general installation instructions
+can be found here:
+
+https://github.com/emmericp/MoonGen
+
+For VSPerf use, MoonGen should be cloned from here (as opposed to the afore
+mentioned GitHub):
+
+git clone https://github.com/atheurer/MoonGen
+
+and use the opnfv-stable branch:
+
+git checkout opnfv-stable
+
+VSPerf uses a particular example script under the examples directory within
+the MoonGen project:
+
+MoonGen/examples/opnfv-vsperf.lua
+
+Follow MoonGen set up instructions here:
+
+https://github.com/atheurer/MoonGen/blob/opnfv-stable/MoonGenSetUp.html
+
+Note one will need to set up ssh login to not use passwords between the server
+running MoonGen and the device under test (running the VSPERF test
+infrastructure). This is because VSPERF on one server uses 'ssh' to
+configure and run MoonGen upon the other server.
+
+One can set up this ssh access by doing the following on both servers:
+
+.. code-block:: console
+
+ ssh-keygen -b 2048 -t rsa
+ ssh-copy-id <other server>
