+.Sh DESCRIPTION
+The
+.Nm
+interface implements the WireGuard point-to-point roaming-capable
+virtual private network tunnel, configured with
+.Xr ifconfig 8
+and
+.Xr wgconfig 8 .
+.Pp
+Packets exchanged on a
+.Nm
+interface are authenticated and encrypted with a secret key negotiated
+with the peer, and the encapsulation is exchanged over IP or IPv6 using
+UDP.
+.Pp
+Every
+.Xr wg 4
+interface can be configured with an IP address using
+.Xr ifconfig 8 ,
+a private key generated with
+.Xr wg-keygen 8 ,
+an optional listen port,
+and a collection of peers.
+.Pp
+Each peer configured on an
+.Nm
+interface has a public key and a range of IP addresses the peer is
+allowed to use for its
+.Nm
+interface inside the tunnel.
+Each peer may also optionally have a preshared secret key and a fixed
+endpoint IP address outside the tunnel.
