 information, and match using this information instead of the built in
 pattern matching function.
 
+You must make a an `intent` entity in the understandings area of wit.ai
+and train it to register certain expressions.
+
+I.e "intent" -> "weather"
+
+Expression: "What is the weather?" and that maps to the weather intent.
+
 Unless you want to directly access the information returned by wit,
 you can use this transparently by enabling bot the `receive` and `hears`
 middlewares.
