-#### Running multiple queries at once
-
-The `runStatements` method will run all the statements at once. This method is an essential tool to reduce the number of database calls, especially when using the HTTP protocol.

-```php
-use Laudis\Neo4j\Databags\Statement;
-
-$results = $client->runStatements([
-    Statement::create('MATCH (x) RETURN x LIMIT 100'),

 ### Transaction functions
 
 Transaction functions are the **de facto** standard when using the driver. It is the most portable as it is resistant to a lot of the pitfalls when first developing with high availability solutions such as [Neo4j aura](https://neo4j.com/blog/neo4j-aura-enterprise-ga-release/) or a [cluster](https://neo4j.com/docs/operations-manual/current/clustering/).
