-## About
+#DOCKER SETUP
 
-The Common Open Research Emulator (CORE) is a tool for emulating
-networks on one or more machines. You can connect these emulated
-networks to live networks. CORE consists of a GUI for drawing
-topologies of lightweight virtual machines, and Python modules for
-scripting network emulation.
-
-## Quick Start

-The following should get you up and running on Ubuntu 18+ and CentOS 7+
-from a clean install, it will prompt you for sudo password. This would
-install CORE into a python3 virtual environment and install
