## Role Variables
This role is designed that the end user should not have to edit the tasks themselves. All customizing should be done via the defaults/main.yml file or with extra vars within the project, job, workflow, etc. These variables can be found [here](https://github.com/ansible-lockdown/RHEL9-CIS/wiki/Main-Variables) in the Main Variables Wiki page. All variables are listed there along with descriptions.
This role is designed that the end user should not have to edit the tasks themselves. All customizing should be done by overriding the required varaibles as found in defaults/main.yml file. e.g. using inventory, group_vars, extra_vars
