-Ansible role for managing Advanced Intrusion Detection Environment (AIDE).
+This is an ansible role that installs and configures the [Advanced Intrusion Detection Environment (AIDE)](https://aide.github.io). For Day 2 tasks it can run integrity checks and update the AIDE database.
+
+## What does this role do for you?
+
+* It ensures that the `aide` package is installed on the remote nodes
+* As an optional task it can generate the `/etc/aide.conf` file and template it out to the remote nodes
+* It initializes the AIDE database
+* The AIDE databases from the remote nodes are stored in a central directory on the controller node
+* It runs AIDE integrity checks on the remote nodes
+* It updates the AIDE databases and stores them 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
 
 ## Requirements
 
-Any prerequisites that may not be covered by Ansible itself or the role should
-be mentioned here.  This includes platform dependencies not managed by the
-role, hardware requirements, external collections, etc.  There should be a
-distinction between *control node* requirements (like collections) and
-*managed node* requirements (like special hardware, platform provisioning).
+This role has no special requirements as it uses `ansible.builtin` modules
+only.
+
+## Role Variables
+
+### aide_db_template
 
-### Collection requirements
+This variable takes a string to specify a path where the custom template for aide.conf is located.
 
-For instance, if the role depends on some collections and has a
-`meta/collection-requirements.yml` file for installing those dependencies, and
-in order to manage `rpm-ostree` systems, it should be mentioned here that the
- user should run
+To be sure that everething is correct, template needs to start with following snippet:
 
-```bash
-ansible-galaxy collection install -vv -r meta/collection-requirements.yml
+``` jinja
+{{ ansible_managed | comment }}
+{{ "system_role:aide" | comment(prefix="", postfix="") }}
 ```
 
-on the *control node* before using the role.
+Default: `null`
 
-## Role Variables
+Type: `string`
 
-A description of all input variables (i.e. variables that are defined in
-`defaults/main.yml`) for the role should go here as these form an API of the
-role.  Each variable should have its own section e.g.
+### aide_db_fetch_dir
 
-### aide_foo
+This variable takes a string to specify the directory on the Ansible Control
+Node (ACN) where the role will store the AIDE database fetched from the remote
+nodes. The default value is `files` which is expected to be a directory in the
+same directory as the playbook.
 
-This variable is required.  It is a string that lists the foo of the role.
-There is no default value.
+In case you like to store the fetched AIDE database files somewhere else you
+need to specify a different path here.
 
-### aide_bar
+Default: `files`
 
-This variable is optional.  It is a boolean that tells the role to disable bar.
-The default value is `true`.
+Type: `string
 
-Variables that are not intended as input, like variables defined in
-`vars/main.yml`, variables that are read from other roles and/or the global
-scope (ie. hostvars, group vars, etc.) can be also mentioned here but keep in
-mind that as these are probably not part of the role API they may change during
-the lifetime.
+### aide_init
 
-Example of setting the variables:
+Initializes the AIDE database.
 
-```yaml
-aide_foo: "oof"
-aide_bar: false
-```
+Default: `false`
 
-## Variables Exported by the Role
+Type: `bool`
 
-This section is optional.  Some roles may export variables for playbooks to
-use later.  These are analogous to "return values" in Ansible modules.  For
-example, if a role performs some action that will require a system reboot, but
-the user wants to defer the reboot, the role might set a variable like
-`aide_reboot_needed: true` that the playbook can use to reboot at a more
-convenient time.
+### aide_fetch_db
 
-Example:
+Fetches database from the remote nodes to store it on the controller node
 
-### aide_reboot_needed
+Default: `false`
 
-Default `false` - if `true`, this means a reboot is needed to apply the changes
-made by the role
+Type: `bool`
+
+### aide_check
+
+Runs an integrity check on the remote nodes
+
+Default: `false`
+
+Type: `bool`
+
+### aide_update
+
+Updates the AIDE database and stores it on the controller node
+
+Default: `false`
+
+Type: `bool`
 
 ## Example Playbook
 
 Including an example of how to use your role (for instance, with variables
 passed in as parameters) is always nice for users too:
 
 ```yaml
-- name: Manage the aide subsystem
-  hosts: all
-  vars:
-    aide_foo: "foo foo!"
-    aide_bar: false
-  roles:
-    - linux-system-roles.aide
