- Renumber deploy.sh steps from [1/5]-[4/5] to [1/4]-[4/4] (step 5 was removed)

 ## Client Configuration
 
+### Finding Your Auth Token
+
+The proxy auth token is the `authToken` value in `config.json` on the server where the proxy runs. To retrieve it:
+
+```bash
+ssh mini-server "node -e \"console.log(JSON.parse(require('fs').readFileSync('/home/harrison/ai-proxy/config.json','utf-8')).authToken)\""
+```
+
+Or just SSH in and read the file directly:
+
+```bash
+ssh mini-server
+cat ~/ai-proxy/config.json | grep authToken
+```
+
+This is the token you'll use in all client configurations below.
