 Qubes OS is a Xen-based operating system meant to provide strong security for desktop computing through secure virtual machines (VMs), also known as *Qubes*.
 
 The Qubes OS operating system secures the computer by isolating subsystems (e.g., networking, USB, etc.) and applications in separate VMs. Should one part of the system be compromised, the extra isolation is likely to protect the rest of the system. For further details see the Qubes [FAQ](https://www.qubes-os.org/faq/).

+## Criteria
+
+**Please note we are not affiliated with any of the projects we recommend.** In addition to [our standard criteria](about/criteria.md), we have developed a clear set of requirements to allow us to provide objective recommendations. We suggest you familiarize yourself with this list before choosing to use a project, and conduct your own research to ensure it's the right choice for you.
+
+!!! example "This section is new"
+
+    We are working on establishing defined criteria for every section of our site, and this may be subject to change. If you have any questions about our criteria, please [ask on our forum](https://discuss.privacyguides.net/latest) and don't assume we didn't consider something when making our recommendations if it is not listed here. There are many factors considered and discussed when we recommend a project, and documenting every single one is a work-in-progress.
+
+Our recommended operating systems:
+
+- Must be open-source.
+- Must receive regular software and Linux kernel updates.
+- Linux distributions must support [Wayland](os/linux-overview.md#Wayland).
+- Must support full-disk encryption during installation.
+- Must not freeze regular releases for more than 1 year. We [do not recommend](os/linux-overview.md#release-cycle) "Long Term Support" or "stable" distro releases for desktop usage.
+- Must support a wide variety of hardware.
