For Coloring on Windows: pip install win_unicode_console colorama


r3con1z3r installs a command line tool on system path that can be interacted with by using

# `domain.com` is the website to perform footprinting on    
r3con1z3r -d domain.com

Using this tool generates a html named as domain.com-r3con1z3r.html which can be opened on a browser to view the footprinting results


Simple usage of r3con1z3r CLI to perform OSINT footprinting on google.com
