+This `rainbird` component allows interacting with [LNK WiFi](http://www.rainbird.com/landscape/products/controllers/LNK-WiFi.htm) module of the Rain Bird Irrigation system in Home Assistant.
+
+To enable it, add the following to your `configuration.yaml` file:
+
+```yaml
+rainbird:
+  host: '1.1.1.1'
+  password: 'XXXXXXX'
+```
+
+Configuration variables:
+
+- **host** (*Required*): The IP address of your LNK WiFi Module.
+- **password** (*Required*): The password for accessing the module.
+
+Finish its configuration by visiting the [Rain Bird sensor](/components/sensor.rainbird/) and [Rain Bird switch](/components/switch.rainbird/) documentation.
+
+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).
