 These instructions are valid for x86-64 computers that do ship with Linux or Windows
 
+Phyllome OS targets x86 systems with hardware-assisted virtualization,
+with a strong preference for those providing IOMMU as well. It may
+support ARM[^49]- or RISC-V-based platforms in the future.
+
+It is expected that Phyllome OS will consume approximately 1 CPU core
+and 1 GB of RAM[^50], which should be enough to accommodate a few
+virtual machines. For instance, on a system with a CPU with 4 cores and
+8 GB of RAM, a guest virtual machine will be able to be assigned up to 3
+cores and 7 GB of RAM.
