# System Settings
The system settings module is available to all administrators under Setup -> System Settings or the gear icon  in the top right corner of the screen. \
\
The settings on this page enables administrators to customise default behaviours in VMS, e.g. *Days extra in port* controls the number of extra days automatically added to new port calls. Note that system settings is applied globally to the environment, which means any change alters the functionality for all users.
