 ## Description 
 
-This script monitors the battery voltage, battery charge current and a GPIO pin. 
+This script monitors the battery voltage, battery charge current.
-+ If battery is low and not charging, or 
++ Can send an alert if battery is not charging or is low.
-+ the pin is pulled down (GND) it initiates a shutdown.
 
 ## Installation
 
 1. **clone** repository to your C.H.I.P. device
 
-        # If not changed: default username "chip" and password "chip".
+2. **copy**
-        ssh chip@<your-device>
-        cd
-        git clone https://github.com/rubienr/chip.git
 
-2. automatically **start** it from **/etc/rc.local**
+    cp ./chipmonk /usr/local/bin/
+    cp ./chipmonk.service /etc/systemd/system/
 
-        #!/bin/sh -e
+4. automatically **start** it using systemd
-        #
-        # rc.local
-        #
-        # This script is executed at the end of each multiuser runlevel.
-        # Make sure that the script will "exit 0" on success or any other
-        # value on error.
-        #
-        # In order to enable or disable this script just change the execution
-        # bits.
-        #
-        # By default this script does nothing.
 
-        # add this line:
+    systemctl enable chipmonk.service
-        /bin/bash /home/chip/chip/chip-off.sh
+    systemctl start chipmonk.service
     
-        exit 0
 
-## Adjustment
+## Use as utility
-The battery low **voltage** and **current levels** are adjustable using:
 
-        # SHUTDOWN_MIN_BATTERY_VOLTAGE ... [mV]
+You may also run script 'chipmonk` without the -d flag to display system stats.
-        SHUTDOWN_MIN_BATTERY_VOLTAGE=2100.0
-        # SHUTDOWN_MIN_BATTERY_VOLTAGE ... [mA]
-        SHUTDOWN_MIN_BATTERY_CURRENT=20.0
-
-The shutdown GPIO pin is adjustable using:
-
-        # see http://docs.getchip.com/#how-you-see-gpio
-        POWER_BUTTON_GPIO_NUMBER="414"
-        POWER_BUTTON_GPIO="/sys/class/gpio/gpio$POWER_BUTTON_GPIO_NUMBER"
