 ## How does the role do that?
 
-* The role is controlled by using [Ansible Tags](https://docs.ansible.com/ansible/latest/playbook_guide/playbooks_tags.html)
+* The role is controlled by using role variables
-* If you run the playbook without specifying any tag the role will change nothing on your remote nodes

-* To execute some supported use cases you need to explicitly specify one or more of the following tags
+* To execute some supported use cases you need to explicitly specify one or more of the following variables
 
 ### Available tags to control and use the role
 
-* __install__ - With this tag the role ensures that the `aide` package is installed on the remote nodes
-* __generate_config__ - Generates the file `/etc/aide.conf` using `templates/aide.conf.j2`; the template needs to be adjusted to fit your requirements; if you do not use this tag the default configuration file shipped with the `aide` package will be used
-* __init__ - Initializes the AIDE database and fetches it from the remote nodes to store it on the controller node
-* __check__ - Runs an integrity check on the remote nodes
-* __update__ - Updates the AIDE database and stores it on the controller node
-
 ## What does this role not do for you?
 
 * It does not explain how to create a good AIDE configuration that suits your requirements; that task remains for you to accomplish
