 Circuit relay consists of two logical parts — dialer/listener and relay (`HOP`). The listener is also known as the `STOP` node. Each of these — dial, listen, and relay — happen on a different node. If we use the nodes from the above example, it looks something like this:

 - And finally we connected the two browser nodes using the `/p2p-circuit/ipfs/...` multiaddr. Take a look at the code below in [src/app.js](src/app.js#L102...L107) - lines 102-107

 The above code snippet handles connecting to other nodes using `ipfs.swarm.connect`. Notice how there wasn't anything special we had to do to use the circuit once we had everything connected; all the magic is in the multiaddr! [Multiaddrs](https://multiformats.io/multiaddr/) are **AWESOME**!
