 ## Prerequisites
-WireGUIde requires a fairly recent version of network-manager, and of course wireguard support. For example, while wireguard is available from buster-backports, network-manager for Debian Buster is too old. WireGUIde is known to work on Debian and Ubuntu versions with network-manager >= 1.22.10. That means taht it will work on Debian Bullseye, Ubuntu Focal and Ubuntu Groovy. Other distros have not been tested yet, but should work if the software running is sufficiently new.

 Also: make sure you are using resolvconf and systemd-resolvd otherwise NetworkManager might empty /etc/resolv.conf when you remove the last tunnel:
