+## Before usage
+### rebuild uImage and rootfs
+```
+make BOARD=t31_lite br-linux-menuconfig
+    Device Drivers
+        Multifunction device drivers
+            <*> Support for the XBurst SADC AUX
+            <*> Support for the XBurst SADC CORE
+make BOARD=t31_lite br-linux-rebuild
+make BOARD=t31_lite br-all
+```
+### or change `br-ext-chip-ingenic/board/t31/kernel/t31.generic.config` before building
+```
+- # CONFIG_MFD_JZ_SADC_V13 is not set
+- # CONFIG_MFD_JZ_SADC_AUX is not set
++ CONFIG_MFD_JZ_SADC_V13=y
++ CONFIG_MFD_JZ_SADC_AUX=y
+
+```
+
+## Options
+```
+-D - sets jz_adc_aux device
+-c - sets the command to call to set night mode
+-d - delay (in seconds) between ADC reads
+-O - turn on night mode when ADC value drops below this threshold
+-F - turn off night mode when ADC value goes above this threshold
+-h - print usage statement and exit
+```
+
+## Examples usage
+```
+autonight -D /dev/jz_adc_aux_0
+autonight -d 3
+autonight -h
+```
+
+## TODO
+### Need to choose the correct default values of `thresholdOn` and `thresholdOff`
