Start with a basic Raspbian install.
- chromium – a browser, that will be run in a full-screen “kiosk” mode
- matchbox – a lightweight, single-window X environment for the browser to run in (starting a full desktop environment would be wasteful)
- x11-xserver-utils – tools to allow configuring the X environment to, for instance, prevent the screen from blanking after several minutes
- unclutter – hide the mouse
