 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,7.0.1
+ansible-galaxy install git+https://github.com/elastic/ansible-elasticsearch.git,7f5be969e07173c5697432141e909b6ced5a2e94
 ```
 
 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.
