:bulb: ***Important Notes:***
- *You might have to check if all the above mentioned roles are available on Ansible Galaxy. If not, please search for the relevant roles and replace them appropriately.*
- *By running the playbook, the roles will handle the installation and configuration of the necessary components for WordPress. Adjust the inventory file to match your server's details, such as the server's IP address and SSH username.*
- *Please note that you may need to provide additional variables or configuration options depending on your specific setup.*
