 useful to isolate network changes (so the host is not affected by the modified
 routing).
 
+This supports directory style (where the certificates are not bundled together in one `.ovpn` file) and those that contains `update-resolv-conf`
+
 ## Usage
 
 Preferably, using `start` in this repository:
 ```bash
-start client_config.ovpn
+start /your/openvpn/directory
 ```
 
+`/your/openvpn/directory` should contain *one* OpenVPN `.conf` file. It can reference other certificate files or key files in the same directory.
+
 Alternatively, using `docker run` directly:
 
 ```bash
-docker run -t -i --device=/dev/net/tun --cap-add=NET_ADMIN \
- --volume client_config.ovpn:/ovpn.conf:ro \
- mook/openvpn-client-socks
+docker run -it --device=/dev/net/tun --cap-add=NET_ADMIN \
+ --volume /your/openvpn/directory/:/etc/openvpn/:ro \
+ kizzx2/openvpn-client-socks
 ```

-### OpenVPN Configuration Constraints
-
-- The configuration file must have embedded certificates; references to other
- files are not allowed.
-- The configuration file must use `dev tun0`.
