+The openweathermap platform uses [OpenWeatherMap](http://openweathermap.org/) as an source for current meteorological data for your location. The `forecast` will show you the condition in 3 h. 
+
+You need an API key which is free but requires a [registration](http://home.openweathermap.org/users/sign_up).
+
+To add OpenWeatherMap to your installation, add the following to your `configuration.yaml` file:
+
+```yaml
+# Example configuration.yaml entry
+sensor:
+  platform: openweathermap
+  api_key: YOUR_API_KEY
+  forecast: 0 or 1
+  monitored_conditions:
+    - weather
+    - temperature
+    - wind_speed
+    - humidity
+    - pressure
+    - clouds
+    - rain
+    - snow
+```
+
+Configuration variables:
+
+- **api_key** (*Required*): Your API key for http://openweathermap.org/.
+- **forecast** (*Optional*): Enables the forecast. The default is to display the current conditions.
+- **display_conditions** array (*Required*): Conditions to display in the frontend.
+  - **weather**: A human-readable text summary.
+  - **temperature**: The current temperature.
+  - **wind_speed**: The wind speed.
+  - **humidity**: The relative humidity.
+  - **pressure**: The sea-level air pressure in millibars.
+  - **clouds**: Description about cloud coverage.
+  - **rain**: The rain volume.
+  - **snow**: The snow volume
+
+Details about the API are available in the [OpenWeatherMap documentation](http://bugs.openweathermap.org/projects/api/wiki).
+
+Only metric measurements are supported at the moment.
