Setting up Neos through sFTP

Hi! I downloaded Neos archive:
https://github.com/neos/neos-development-collection/releases/download/2.2.0/Neos-2.2.0.tar.gz

Then extracted the contents and uploaded them in the public_html folder of the server via sFTP.

How do I now get the Neos website to work??? When I go to my site - sitename.com, it is still showing the “403 Forbidden You don’t have permission to access / on this server.” - the same error when the server was empty.

And when I go to sitename.com/Web, I get “500 Internal Server Error” and sitename.com/neos or sitename.com/setup gives “404 Not Found”.

Thank you!
