 # Openvpn with torrent client
 
-Just add your openvpn configuration `config.ovpn` and the authorization file
-`auth.txt` and modify `config.ovpn` to use the auth file: `auth-user-pass /opt/auth.txt`
+Put configuration files into `/etc/openvpn/client` and create
+a file `/etc/openvpn-aria2.conf`:
 
-Next run `./start` to drop into a shell as your user in your home directory.
-Now you can use aria2 to download everything over a VPN.
+```
+OVPN_CONFIGURATION_FILE=#name of file in /etc/openvpn/client, NOT the full path
+```
+
+Run `make build` to generate the docker image and `./start` to start
+connect to the vpn inside the image.
+
+`make install` installs the start script under `/usr/local/bin/openvpn-aria2`.
