 ### On the client ("simple" approach, Make-based)
 
 1. Get the `client.ovpn` file from the server and put it into the `client` directory.
-2. Run `make start`, enter your GSocket server secret and then your sudo password (if necessary).

 3. To stop the client, run `make stop.`
 
 ### On the client (manual approach, POSIX)
 
 1. Get the `client.ovpn` file from the server.
-2. Run these commands directly: `gs-netcat -D -s your_gsocket_secret -p 1194 && sudo openvpn --daemon gs-warp --config client.ovpn`
-3. To stop, first stop the OpenVPN process and then gs-netcat.

+3. Run these commands directly: `gs-netcat -D -s $GS_SECRET -p 1194 && sudo openvpn --daemon gs-warp --config client.ovpn`
+4. To stop, first stop the OpenVPN process and then gs-netcat.
 
 ### On the client (manual approach, non-POSIX)
 
 This is suitable for non-POSIX environments. You'll need any OpenVPN client and `gs-netcat` binary for your platform.
 
 1. Get the `client.ovpn` file from the server and put it into your OpenVPN client's profile. Do not start the client yet.
-2. In a separate terminal window, run `gs-netcat -D -s your_gsocket_secret -p 1194`.
-3. Start the OpenVPN connection in the client.
-4. To stop, first stop the OpenVPN connection and then terminate the gs-netcat process.
