+# Script: updates-aurhelper
+
+A script that shows if there are AUR updates for Arch Linux.
+
+
+## Dependencies
+
+The possibilities depend on your AUR helper. Not all helpers can report the pending updates.
+
+At the moment `yay`, `paru`, `trizen`, `pikaur`, `rua` and `cower` are documented. Take a look at the script to see how it works.
+
+
+## Module
+
+```ini
+[module/updates-aurhelper]
+type = custom/script
+exec = ~/polybar-scripts/updates-aurhelper.sh
+interval = 600
+```
