 Lets install our first package! To do so, enter `sudo dnf install cmatrix`. You will be asked for the password of your user. Type the password and then press `Enter`.

 Sometimes, an action might not modify the system, but a user might be restricted through the permissions system to not be able to access a file for example. In this case, you would also need to use `sudo`.
