-#### Getting necessary permissions

-A regular Linux user is allowed to use pacman to get information. This includes

-Only the user `root` is allowed to use pacman to update, install or remove

-Thus a pacman call like `pacman -Syu` should be rewritten to `sudo pacman -Syu`

 #### Package removal
 
 The recommended command to remove one or multiple packages is:

-The options `-Rs` select removal with `R` and recursive with `s`. The latter
