+
+The `ness_alarm` component will allow Home Assistant users who own a Ness D8x/D16x alarm system to leverage their alarm system and its sensors to provide Home Assistant with information about their homes. Connectivity between Home Assistant and the alarm is accomplished through a IP232 module that must be connected to the alarm.
+
+There is currently support for the following device types within Home Assistant:
+
+- [Binary Sensor](/components/binary_sensor.ness_alarm/): Reports on zone statuses
+- [Alarm Control Panel](/components/alarm_control_panel.ness_alarm/): Reports on alarm status, and can be used to arm/disarm the system
+
+The module communicates via the [Ness D8x/D16x ASCII protocol](http://www.nesscorporation.com/Software/Ness_D8-D16_ASCII_protocol.pdf).
+
+## {% linkable_title Configuration %}
+
+A `ness_alarm` section must be present in the `configuration.yaml` file and contain the following options as required:
