+### Detect AUR package rebuilds
+
+Install the package `extra/rebuild-detector`  
+It will create a `pacman` hook to check which packages need to be rebuild, but can also be executed with the following command.
+
+[shuser]
+
+```sh
+checkrebuild
+```
+
+[/shuser]
+
+The packages might be rebuilt automatically a lot of the time, but sometimes it is necessary to for a rebuild using the AUR helper.  
+This is an example using `paru`
+
+[shuser]
+
+```sh
+paru -S --rebuild=yes <package>
+```
+
+[/shuser]
