+# 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`
+
+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.
