-## Support level
-Full support for base board but not any extension board on the
-GPIOs.
-
-### Touch screen
-The [Raspberry Pi touch display v1][RPI-TOUCH] is supported, including
-touch functionality. There are multiple touchscreens on the market for
-Raspberry Pi, but only the official (first version with 800x480
-resolution) is currently supported. Infix supplies all drivers
-required to utilize the hardware, but you need to add the actual
-graphical application in a container.
-
-There are some important considerations you need to know about when
-using Infix for graphical applications. The container needs access to
-/dev/dri/ to be able to access the graphics card, and it also needs
-access to /run/udev to be able to find the input devices.
