-In order for our browser nodes to be able to messages each other, we need to get them connected. But do do that, we need to use a relay - browser nodes can't be connected directly because of lack of socket support.

 Remember the caveat above `Currently a Relay will only work if it already has a connection to the STOP node`? This means that we need to connect our browser nodes to the relay node first.

-Now that both browsers are running side by side (as shown in the first screenshot), let's get them connected to each other.

+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**!
 
 I encourage the reader to take a look at the bundled app code to see how the browser nodes get setup, suffice to say nothing changes from the perspective of using an `IPFS` node in js code, apart from the new `EXPERIMENTAL` options.
