+Cluster support is always available when directly connecting to the responsible servers. If you do not need to fine tune these connections, autorouting is available for all connections:
 
 ```php
 use Laudis\Neo4j\Network\Bolt\BoltInjections;
+use Laudis\Neo4j\Network\Http\HttpInjections;
 
 $client = Laudis\Neo4j\ClientBuilder::create()
     ->addBoltConnection(
         'main',

          BoltInjections::create()->withAutoRouting(true)
      )

     ->build();
 
 $client->run('RETURN 1'); // will run over a random follower found in the routing table
 $client->run('MERGE (x:Y {z: 0)'); //will run over a random leader found in the routing table
 $client->run('RETURN 1', [], 'backup'); //will run over the non replicated server
 $client->run('RETURN 1', [], 'main'); //will be autorouted
+$client->run('RETURN 1', [], 'http'); //will be autorouted
 ```
 
-NOTE: http cluster support will be available in the next minor release and will have practically the same api.
