-- how full/empty is the battery?
-- how do i change the display brightness?
-
-  brightnessctl s [1-7]
-  
-- what temperature does the cpu/system have?
-
-  cat /sys/class/thermal/thermal_zone0/temp
-  
-- how do i use the proprietary hardware video decoder?
-
-- what does the boot rom do?
-- where are the schematics for tinyRex?
-- where are the schematics for REFORM?
-
-  The schematics of the motherboard, keyboard and trackball are in the git repository https://github.com/mntmn/reform
-  
-- how do i use an LTE modem/WWAN?
-
-  The only modem tested so far is Huawei XYZ999. It presents itself as 5 serial ports (tty*) and an ethernet device in the system.
-  You have to connect with a serial terminal like screen to /dev/tty* and issue AT commands to unlock the SIM and connect to the internet.
-  
-- how do i setup WiFi on the console?
-
-  wicd-curses
-  
-- can i use a discrete graphics card by nvidia or amd?
-- what is the resolution of the display?
-
-The internal display has a resolution of 1366x768, but it is configured in the device tree (DTS) as 1368x768 to avoid problems with graphics drivers/hardware that can only handle multiples of 8 as the width.
-  
-- what is the maximum resolution of HDMI?
-
-The maximum tested resolution of the HDMI output is 1920x1200.
-  
-- how do i use the microphone input in the headphone jack?
-- where are the speakers?
-
-Reform does not include any speakers, but a stereo speaker module is in the making. You can also build your own by connecting an amplifier and speakers to the motherboard header labelled Line Out.

-- how do i use SPI, I2C, GPIO?
-- how do i use CSI, DSI?
-- how can i use the bootrom's usb device mode?
-- how do i print/make my own case part?
-- how do i make a new keycap?
-- how to use OpenGL/ES hardware acceleration in Xorg?
-- how to use OpenGL/ES hardware acceleration in wayland?
-- software/game XYZ does not work, is there a workaround?
-- how can i run x86 software?
-- how can i run Raspberry Pi compatible software?
