-## RedHat/CentOS 7 with Python 3
-
-CentOS/RedHat 7 is pretty old. Python 3 got added after the initial release and
-a lot of packages are missing. For example python3.6 is available as a package,
-but no matching wsgi module for apache is available. Because of that, we don't
-test on CentOS 7 anymore. However, it's still possible to setup Puppetboard on
-CentOS with gunicorn as a webserver and nginx/apache forwarding to it.
