 There is currently support for the following device types within Home Assistant:
 
+- [Binary Sensor](#binary-sensor)
 - [Sensor](#sensor)
 - [Switch](#switch)
 
-## Configuration
+{% include integrations/config_flow.md %}
 
-To enable it, add the following to your `configuration.yaml` file:
+## Configuration Options
 
-```yaml
-# Example configuration.yaml entry
-rainbird:
-  host: IP_ADDRESS_OF_MODULE
-  password: YOUR_PASSWORD
-  trigger_time: 360
+The integration has a configuration option to change the default amount of time that the irrigation
+will run when turning on a zone switch (default is 6 minutes). This can be overridden with a service call (see below).
 
-```

-Please note that due to the implementation of the API within the LNK Module, there is a concurrency issue. For example, the Rain Bird app will give connection issues (like already a connection active).

+The `rainsensor` sensor will tell if you if the device has detected rain.
 
 ## Sensor
 
-This `rainbird` sensor allows interacting with [LNK WiFi](https://www.rainbird.com/products/lnk-wifi-module) module of the Rain Bird Irrigation system in Home Assistant.
-
-The integration adds `rainsensor` and `raindelay` sensors and their `binary_sensor` alternatives.
+The `raindelay` sensor reports the number of days, if any, the automatic irrigation schedule
+has been delayed.
 
 ## Switch
 
-This `rainbird` switch platform allows interacting with [LNK WiFi](https://www.rainbird.com/products/lnk-wifi-module) module of the Rain Bird Irrigation system in Home Assistant.
-
 Switches are automatically added for all available zones of configured controllers.
 
 ## Services
 
-The Rain Bird switch platform exposes a service to start a single irrigation for a given duration.
+The integration exposes services to give additional control over a Rain Bird device.
 
-| Service | Description |
-| ------- | ----------- |
-| rainbird.start_irrigation | Set a duration state attribute for a switch and turn the irrigation on.|
-| rainbird.set_rain_delay | Set how long automatic irrigation is turned off.|
+### `rainbird.start_irrigation`
+
+Start a Rain Bird zone for a set number of minutes. This service accepts a Rain Bird sprinkler
+zone switch entity and allows a custom duration unlike the switch.
+
+| Service Data Attribute | Optional | Description                                           |
