This will be a nice article (and shortly) because always a developer like me wants to say "I participate on that proyect" and should be nice say it. So some guys made the "humans.txt" the project page is humanstxt.org.
But ... What's humants.txt?
Well I'll quote the answer. "It's an initiative for knowing the people behind a website. It's a TXT file that contains information about the different people who have contributed to building the website."
