 ## Example usage
 
-In three separate tabs, run consecutively:
+For dev usage, generate a self-signed certificate and run the server:
 
 ```console
 $ ./generate_cert.sh
 $ ./simple_server.py
 ```
 
+If you want to use this server from the browser (to use the JS example, for
+instance), you will need to go to `https://127.0.0.1:8443` and accept the
+self-signed certificate. This step is not required if you will be deploying on
+a server with a CA-signed certificate, in which case you should use
+`./simple_server.py --cert-path <cert path>`.
