+	help
+	  WireGuard is an extremely simple yet fast and modern VPN
+	  that 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. Initially released for the Linux kernel, it
+	  plans to be cross-platform and widely deployable. It is
+	  currently under heavy development, but already it might be
+	  regarded as the most secure, easiest to use, and simplest
+	  VPN solution in the industry.
