+The main configuration you *should* include are the `PeerId` and `Multiaddrs`, which are detailed next. Using a consistent PeerId will ensure your node's identity is consistent across restarts, and the Multiaddrs will allow you to appropriate bind your local and external addresses so that other peers can connect to you.
 
 #### PeerId
 
 You can create a [PeerId](https://github.com/libp2p/js-peer-id) via its [CLI](https://github.com/libp2p/js-peer-id#cli). 
 
+Once you have a generated PeerId json file, you can start the relay with that PeerId by specifying its path via the `--peerId` flag:
 ```sh
-libp2p-relay-server --peerId id.json
+libp2p-relay-server --peerId /path/to/peer-id.json
 ```
 
 #### Multiaddrs
 
-You can specify the libp2p rendezvous server listen and announce multiaddrs. This server is configured with [libp2p-tcp](https://github.com/libp2p/js-libp2p-tcp) and [libp2p-websockets](https://github.com/libp2p/js-libp2p-websockets) and addresses with this transports should be used. It can always be modified via the API.
