 Create your Ansible playbook with your own tasks, and include the role elasticsearch. You will have to have this repository accessible within the context of playbook.
 
 ```sh
-ansible-galaxy install elastic.elasticsearch
+ansible-galaxy install elastic.elasticsearch,6.6.0
 ```
 
 Then create your playbook yaml adding the role elasticsearch. By default, the user is only required to specify a unique es_instance_name per role application.  This should be unique per node.
