 #### Running PeerServer behind a reverse proxy
 
-Make sure to set the `proxied` option.
+Make sure to set the `proxied` option, otherwise IP based limiting will fail.
 The option is passed verbatim to the
 [expressjs `trust proxy` setting](http://expressjs.com/4x/api.html#app-settings)
 if it is truthy.

-node ./src/index.js --port 9000 --path /myapp --proxied true

+### Events
+
+The `'connection'` event is emitted when a peer connects to the server.
+
+```javascript
+peerserver.on('connection', (client) => { ... });
+```
+
+The `'disconnect'` event is emitted when a peer disconnects from the server or
+when the peer can no longer be reached.
+
+```javascript
+peerserver.on('disconnect', (client) => { ... });
