-# PeerJS: a WebRTC PeerConnection/DataChannel library #
+# PeerJS: Peer-to-peer data in the browser #
+
+##[http://peerjs.com](http://peerjs.com)
+
+PeerJS wraps the WebRTC implementation to provide a complete, configurable, and easy-to-use peer-to-peer data API. Each peer simply provides a identifier with which other peers using the same API key can connect.
+
+

+
+`<script>
+  var peer = new Peer('someid', {key: 'apikey'});
+  peer.on('connection', function(conn) {
+    conn.on('data', function(data){
+      // Will print 'hi!'
+      console.log(data);
+    });
+  });
+</script>`

+Connecting peer
+
+`<script>

+  conn.on('open', function(){
+    conn.send('hi!');
