 This plugin provides Botkit developers a way to use the [rasa NLU](https://rasa.ai/) open source, self hosted natural language API.

+## Setup
+
+Add botkit-rasa as a dependency to your Botkit-bot.
+`npm install botkit-rasa`
+
+Enable the middleware:
+
+```javascript 
+    var rasa = require('botkit-rasa')({
+        rasa_uri: "my_rasa_url",//if no url was provided http://localhost:5000 will be used.
+        project: "my_project",//project to use, if no project was provided project won't be used in the request.
+        model: "my_model"//model to use, if no model was provided model won't be used in the request.
+        });
+
+    //if you chose to not include the project or the model you should adapt your rasa_uri to include these
+    //mind the 'parse' route in this case.
+   var rasa = require('botkit-rasa')({
+       rasa_uri: "localhost:5000/parse?&model=<model>&project=<project>"
+       });
+
+    controller.middleware.receive.use(rasa.receive);
 
+    //Eventually set rasa hears as the standard hears method.
+    controller.changeEars(rasa.hears);
+```
+Setup a controller to use the hears middleware.
+```javascript
+controller.hears(['my_intent'],'message_received', rasa.hears, function(bot, message) {
     console.log('Intent:', message.intent);
     console.log('Entities:', message.entities);
