+
+The `arwn` sensor platform is a client for the
+[Ambient Radio Weather Network](http://github.com/sdague/arwn)
+project. This collects weather station data and makes it available in
+an MQTT subtree.
+
+To use your ARWN setup, you must already have configured the
+[MQTT](mqtt) platform. Then add the following to your
+`configuration.yaml` file:
+
+```yaml
+# Example configuration.yaml entry
+sensor:
+  platform: arwn
+```
+
+Currently all temperature, barometer, and wind sensors will be
+displayed. Support for rain guage sensors will happen in the future.
