 This example comes with 3 main files. A `relay.js` file to be used in the first step, a `listener.js` file to be used in the second step and a `dialer.js` file to be used on the third step. All of these scripts will run their own libp2p node, which will interact with the previous ones. All nodes must be running in order for you to proceed.
