 ## Why collect them
 
 The fields in /etc/os-release are standardized, but the values are not. The only way to know that Redhat Enterprise Linux is 'rhel' or that openSUSE 15 is 'opensuse-leap' is to install the distros and check the file. This repo is a large collection of os-release files so you don't need to install each and every distro.
