+
+This package contains a factory method to create a Elasticsearch client from [ruflin/elastica](https://github.com/ruflin/Elastica).
+The factory supports DSN to ease config with a dependency injection container. 
+
+## Install
+
+```
+composer require happyr/elastica-dsn
+```
+
+## Examples
+
+```php
+use Happyr\ElasticaDsn\ClientFactory;
+
+$client = ClientFactory::create('elasticsearch://localhost');
+$client = ClientFactory::create('elasticsearch:?host[localhost]&host[localhost:9201]&host[127.0.0.1:9202]');
+$client = ClientFactory::create('elasticsearch://foo:bar@localhost:1234');
+$client = ClientFactory::create('elasticsearch://localhost:9201', ['username' => 'foo', 'password' => 'bar']);
+```
+
+If you use Symfony service config:
+
+```yaml
+services:
+    Elastica\Client:
+        factory: 'Happyr\ElasticaDsn\ClientFactory::create'
+        arguments: ['elasticsearch://localhost']
+```
+
+If you want to configure the client even more, you may just get the config array from the `ClientFactory` and
+instantiate the client yourself. 
+
+```php
+use Elastica\Client;
+use Happyr\ElasticaDsn\ClientFactory;
+
+$config = ClientFactory::getConfig('elasticsearch://localhost');
+
+// Add more stuff to $config array
+$client = new Client($config);
+```
