+# ntp-client [![Build Status](https://secure.travis-ci.org/moonpyk/node-ntp-client.png?branch=master)](http://travis-ci.org/moonpyk/node-ntp-client)
+
+Pure Javascript implementation of the NTP Client Protocol
+
+## Getting Started
+Install the module with: `npm install ntp-client`
+
+```javascript
+var ntpClient = require('ntp-client');
+
+ntpClient.getNetworkTime("pool.ntp.org", 123, function(err, date) {
+    if(err) {
+        console.error(err);
+        return;
+    }
+
+    console.log("Current time : ");
+    console.log(date); // Mon Jul 08 2013 21:31:31 GMT+0200 (Paris, Madrid (heure d’été))
