When the Welcome Screen feature is turned on, the settings from the [[Welcome Screen|doc/first_steps/welcome_screen]] are saved in the Persistent Storage: language, keyboard, and additional settings.
When the Additional Software feature is turned on, a list of [[additional software|additional_software]] of your choice is automatically installed every time you start Tails.
On Tails and Linux in general, the name of configuration files often starts with a dot and are sometimes called [[!wikipedia dotfiles]] for this reason.The Dotfiles feature of the Persistent Storage makes it easy to persist such "*dotfiles*", for example */home/amnesia/.gitconfig* or */home/amnesia/.bashrc*.
If you have more than one display (for example, two monitors or a projector), you can save the configuration of your displays using the **Dotfiles** feature.
