 ## Limitations
 * Not dual stack, clients can only be shaped by IPv4 address for now in v0.9. Once IPv6 support is added to <a href="https://github.com/xdp-project/xdp-cpumap-tc">XDP-CPUMAP-TC</a> we can then shape IPv6 as well.
 * Working on stats feature
+## Requirements
+* Requires XDP-CPUMAP-TC. <a href="https://github.com/rchac/LibreQoS/tree/main/v0.9-alpha">See here</a> for details.
+* Only works on dedicated linux machine at the moment, not on VMs. Will soon work on VMs once <a href="https://www.spinics.net/lists/bpf/msg42260.html">this patch</a> is part of the mainline linux kernel.
