+define Package/wireguard/Default/description
+ WireGuard is a novel VPN that runs inside the Linux Kernel and utilizes
+ state-of-the-art cryptography. It aims to be faster, simpler, leaner, and
+ more useful than IPSec, while avoiding the massive headache. It intends to
+ be considerably more performant than OpenVPN. WireGuard is designed as a
+ general purpose VPN for running on embedded interfaces and super computers
+ alike, fit for many different circumstances. It uses UDP.
