+Package elasticsearch provides a Go client for Elasticsearch.
+
+Create the client with the NewDefaultClient function:
+
+		elasticsearch.NewDefaultClient()
+
+The ELASTICSEARCH_URL environment variable is used instead of the default URL, when set.
+Use a comma to separate multiple URLs.
+
+To configure the client, pass a Config object to the NewClient function:
+
+		cfg := elasticsearch.Config{
+		  Addresses: []string{
+		    "http://localhost:9200",
+		    "http://localhost:9201",
+		  },
+		  Username: "foo",
+		  Password: "bar",
+		  Transport: &http.Transport{
+		    MaxIdleConnsPerHost:   10,
+		    ResponseHeaderTimeout: time.Second,
+		    DialContext:           (&net.Dialer{Timeout: time.Second}).DialContext,
+		    TLSClientConfig: &tls.Config{
+		      MinVersion:         tls.VersionTLS11,
+		    },
+		  },
+		}
+
+		elasticsearch.NewClient(cfg)
+
+When using the Elastic Service (https://elastic.co/cloud), you can use CloudID instead of Addresses.
+
+See the elasticsearch_integration_test.go file and the _examples folder for more information.
+
+Call the Elasticsearch APIs by invoking the corresponding methods on the client:
+
+		res, err := es.Info()
+		if err != nil {
+		  log.Fatalf("Error getting response: %s", err)
+		}
+
+		log.Println(res)
+
+See the github.com/elastic/go-elasticsearch/esapi package for more information and examples.
