+Summary:Next generation secure VPN network tunnel
+Description:
+WireGuard is a next generation secure network tunnel protocol. This application
+allows users to connect to WireGuard tunnels. More information may be found on
+the [project webpage https://www.wireguard.com].
+
+If your device has a custom kernel containing the WireGuard module, then the
+module will be used for superior battery life and performance. Otherwise a
+userspace version will work sufficiently on all other devices.
