+## Rain 
+
+Quietly judges your choice of climate.
+
+### Description
+
+It's a well documented fact that looking out of the window is sometimes far too much effort. However, sometimes you just need toknow how wet it is outside: this module queries for the precipitation level, and tells you when you need a raincoat.
+
+### Configuration
+#### apikey
+This module requires a Wunderground API key. You can register for one, for free, at http://www.wunderground.com/weather/api/
+
+### Commands
+
+#### ~rain
+Polls the rainfall in the last hour, and returns an appropriate string.
