 Additional recommendations
 --------------------------

 - It is recommended to set reasonable constraints on memory (`-m`) and CPU cores (`--cpus`), especially on less

+- `--privileged` is mandatory for underlying `Mininet <https://mininet.org/>`__ to utilize the virtual switch
 - The root directory on `run` is `/mini-ndn`, which contains the installation and examples.
 - The GUI may not work for now due to docker and xterm setup issues and is independent from Mini-NDN.
   If you intend to run the GUI, pass `-e DISPLAY -v /tmp/.X11-unix:/tmp/.X11-unix` to the `docker run` command.

 What is Mini-NDN?
 -----------------
 
 Mini-NDN is a lightweight networking emulation tool that enables testing, experimentation, and
-research on the NDN platform. It was initially based on `Mini-CCNx <https://github.com/chesteve/mn-ccnx>`_ which was a fork of `Mininet <https://github.com/mininet/mininet>`_. Mini-NDN uses the NDN libraries, NFD, NLSR, and tools released by the `NDN project <http://named-data.net/codebase/platform/>`_ to emulate an NDN network on a single system.
