+[![Build Status](https://travis-ci.org/elastic/elasticsearch-php.svg?branch=master)](https://travis-ci.org/elastic/elasticsearch-php) [![Latest Stable Version](https://poser.pugx.org/elasticsearch/elasticsearch/v/stable)](https://packagist.org/packages/elasticsearch/elasticsearch) [![Total Downloads](https://poser.pugx.org/elasticsearch/elasticsearch/downloads)](https://packagist.org/packages/elasticsearch/elasticsearch)
+
+Official low-level client for Elasticsearch. Its goal is to provide common ground for all Elasticsearch-related code in PHP; because of this it tries to be opinion-free and very extendable.
+
+To maintain consistency across all the low-level clients (Ruby, Python, etc.), clients accept simple associative arrays as parameters.  All parameters, from the URI to the document body, are defined in the associative array.
+
+Starting from version 7.4.0, all the endpoints (and namespaces) are autogenerated using the [util/GenerateEndpoints.php](https://github.com/elastic/elasticsearch-php/blob/master/util/GenerateEndpoints.php) script. This script reads the [Elasticsearch API specs](https://github.com/elastic/elasticsearch/tree/master/rest-api-spec/src/main/resources/rest-api-spec/api) and generated the PHP classes for all the endpoints.
