ChromeOS is the Linux-based operating system that is found on Chromebooks, made by Google. It uses the Google Chrome browser as the main interface.
ChromeOS Flex is the same operating system meant for installation on PCs and Apple computers, and is provided for free.
ChromeOS is not considered a typical GNU/Linux distribution like Debian or Fedora, because the main interface is just the Chrome browser. So my question is: are questions about using ChromeOS and ChromeOS Flex on-topic here at Unix & Linux StackExchange? If they are not on-topic here, which StackExchange website would they be a good fit for?
