+The @code{(gnu services vpn)} module provides services related to
+@dfn{virtual private networks} (VPNs). It provides a @emph{client} service for
+your machine to connect to a VPN, and a @emph{servire} service for your machine
+to host a VPN. Both services use @uref{https://openvpn.net/, OpenVPN}.
+
+@deffn {Scheme Procedure} openvpn-client-service @
