+# Sager Weathercaster Binding
+
+The Sager Weathercaster is a scientific instrument for accurate prediction of the weather. 
+
+## Limitations
+
+* To operate, this binding will need to use channel values provided by other means (e.g. Weather Binding, Netatmo, a 1-Wire personal weather station...)
+
+* This binding buffers readings for some hours before producing weather forecasts(wind direction and sea level pressure). SagerWeatherCaster needs an observation period of minimum 6 hours.
+
+For these reasons, this binding is not a binding in the usual sense.
+
+## Discovery
+
+A default `sagercaster` thing will be automatically discovered, based on system location.
+
+## Binding Configuration
+
+The binding itself does not require any configuration.
+
+## Thing Configuration
+
+### SagerCaster
+
+| Name               | Type     | Description                                                              |
+|--------------------|----------|--------------------------------------------------------------------------|
+| location           | Location | Latitude and longitude of the desired weather forecast.                  |
+| observation-period | int      | Minimum delay (in hours) before producing forecasts. Defaulted to 6.     |
+
+## Channels
+
+The binding will use some input channels, that can be configured directly with profiles (sample below).
+
+| Name                | Group  |Type                 | Description                                                     |
