 # run the server
-python server.py
+python server.py --localhost
 ```
+For the server to be accessible by other people I reccomend using [ngrok](https://ngrok.com).
+
+Once you have downloaded ngrok, follow it's instructions to connect to your account, then run
+```bash
+ngrok tcp 11000
+```
+It should boot up ngrok and there will be a url and port, you need to give this url and port to other people. (Note: you need to connect with the ip 127.0.0.1 and port 11000).
