 The following helpers are supported and automatically selected, if present, in the order listed below:
 - [yay](https://github.com/Jguer/yay)
-- [aurman](https://github.com/polygamma/aurman)
-- [pacaur](https://github.com/rmarquis/pacaur)

 *makepkg* will be used if no helper was found or if it is explicitly specified:

 * Either *name* or *upgrade* is required, both cannot be used together.
-* *skip_installed* cannot be used with *upgrade*.
 * In the *use*=*auto* mode, makepkg is used as a fallback if no known helper is found.
 
 ## Installing
@@ -37,39 +37,43 @@ Just clone the *ansible-aur* repository into your user custom-module directory:
 git clone https://github.com/kewlfft/ansible-aur.git ~/.ansible/plugins/modules/aur

+### Ansible Galaxy
+*ansible-aur* is available in Galaxy which is a hub for sharing Ansible content. To download it, use:
+```
+ansible-galaxy install kewlfft.aur
+```
+
+Note that if this module is installed from Ansible Galaxy, you will need to list it explicitly in your playbook:
+```
+# playbook.yml
+- hosts: localhost

+  - kewlfft.aur
+  tasks:

 ## Usage
 ### Notes
-* This module aims to cover the AUR; for package removal or system upgrade with the repositories, it is recommended to use the official *pacman* module.
-* The *--needed* parameter of the helper is systematically used, it means if a package is up to date, it is not built and reinstalled.
-
-### Examples
-Use it in a task, as in the following examples:
-```
-# Install trizen using makepkg, skip if trizen is already installed
-- aur: name=trizen use=makepkg skip_installed=true
-  become: yes
-  become_user: aur_builder
-
-# Install package_name using the first known helper found
-- aur: name=package_name
-  ...
-
-# Install package_name_1 and package_name_2 using trizen
-- aur:
-    use: trizen
-    name:
-      - package_name_1
-      - package_name_2
-  ...
-
-# Upgrade - using pacaur
-- aur: upgrade=yes use=pacaur
-  ...
-```
+* The scope of this module is installation and update from the AUR; for package removal or for updates from the repositories, it is recommended to use the official *pacman* module.

 ### Create the "aur_builder" user
-While Ansible expects to SSH as root, AUR helpers do not allow executing operations as root, they all fail with "you cannot perform this operation as root". It is therefore recommended to create a user, let's call it *aur_builder*, that has no need for password with pacman in sudoers.
-This can be done in Ansible with the following actions:
