 node-elasticsearch
-============
+==================
 
-This is a module around the REST API for [Elastic Search](http://www.elasticsearch.org/) built for NodeJS.
+This is a Node.js module for the [elasticsearch](http://www.elasticsearch.org/) REST API.
 
 
-Details
-=============
+Usage
+=====
 
-This works with node 0.4.x and with 0.2.x. I needed it for both and so wrote an [http compatability layer](http://github.com/ncb000gt/node-http_compat).
+```js
+var elasticsearch = require('elasticsearch');
+var es = elasticsearch({index: 'kitteh'});
 
+es.query({query: {field: {field1: 'hai'}}}, function(err, results) {
+  console.log(results);
+});
+```
 
-Usage
-=============
 
-     var lib = require('elasticsearch'), sys = require('sys'); //replace sys with util if you're on node 0.4.x
-     lib.createClient(function(client) {
-         client.query({query: {field: {field1: 'hai'}}}, function(err, results) {
-             console.log(sys.inspect(results, true, 10));
-         });
-     });
+API
+===
 
+TBD
