+Warning: This is experimental.
 
 ## Usage
 
+Minimal example, Hypercore replication via WebRTC:
+
+```js
+swarm.on('connection', function (relay) {
+  // Convert the relayed socket into a RTCDataChannel stream
+  const stream = HyperWebRTC.from(relay)
+  core.replicate(stream)
+})
+
+// Split RTC traffic from UDX traffic
+const discoveryWeb = crypto.discoveryKey(core.discoveryKey)
+swarm.join(discoveryWeb)
+````
+
+Another minimal example, DHT server and client:
+
+```js
+server.on('connection', function (relay) {
+  // Convert the relayed socket into a RTCDataChannel stream
+  const rtc = HyperWebRTC.from(relay)
+})
+
+const relay = dht.connect(server.publicKey)
+const rtc = HyperWebRTC.from(relay) // Convert it here also
+```
+
+## DHT example
+
+```js
+import HyperWebRTC from 'hyper-webrtc'
+
+import DHT from '@hyperswarm/dht-relay'
+import Stream from '@hyperswarm/dht-relay/ws'
+
+const node = createDHTRelay()
+const server = node.createServer()
+
+server.on('connection', function (relay) {
+  const rtc = HyperWebRTC.from(relay)
+
+  rtc.on('data', function (data) {
+    console.log('Server-side received', data.toString())
+  })
+})
+
+await server.listen()
+
+const anotherNode = createDHTRelay()
+const relay = anotherNode.connect(server.publicKey)
+const rtc = HyperWebRTC.from(relay)
+
+rtc.on('open', function () {
+  console.log('Client-side opened')
+})
+
+rtc.write('Hello World!')
+
+function createDHTRelay () {
+  const socket = new WebSocket('wss://dht1-relay.leet.ar:49443')
+  const dht = new DHT(new Stream(true, socket))
+  return dht
+}
+```
