 # battery_status_led
 Battery (low/critical) status indication by making a (the capslock) LED blink
+
+Make sure you have your laptop's ACPI module compiled into your kernel:
+Device Drivers > X86 Platform Specific Device Drivers
+For example: Asus laptop extras, ThinkPad ACPI Laptop Extras, etc.
+
+Start it as root user:
+/usr/bin/battery_status_led.sh
+
+Or with systemd:
+systemctl start battery_status_led
+systemctl enable battery_status_led
+
+The LED device can be changed by editing the systemd service file's line:
+Environment="BATTERY_STATUS_LED_DEV=/sys/class/leds/input4\:\:capslock"
