 # How to use WireGuard 
-The container will fail to boot if `VPN_ENABLED` is set and there is no valid .conf file present in the /config/wireguard directory. Drop a .conf file from your VPN provider into /config/wireguard and start the container again. The file must have the name `wg0.conf`.

 # How to use OpenVPN
-The container will fail to boot if `VPN_ENABLED` is set and there is no valid .ovpn file present in the /config/openvpn directory. Drop a .ovpn file from your VPN provider into /config/openvpn and start the container again. You may need to edit the ovpn configuration file to load your VPN credentials from a file by setting `auth-user-pass`.
+The container will fail to boot if `VPN_ENABLED` is set and there is no valid .ovpn file present in the /config/openvpn directory. Drop a .ovpn file from your VPN provider into /config/openvpn (if necessary with additional files like certificates) and start the container again. You may need to edit the ovpn configuration file to load your VPN credentials from a file by setting `auth-user-pass`.
 
 **Note:** The script will use the first ovpn file it finds in the /config/openvpn directory. Adding multiple ovpn files will not start multiple VPN connections.
