 You first need to instanciate a YodelEngine "super" object which will define which xml file you'll be using. It has only one parameter, the absolute path to your xml file, which we usually call routes.xml .
 
 ```
-ydl = Yodel("path/to/your/routes.xml"))

 Well, now you actually need to write that file. Just look at the example we gave you above : each <route /> represents a route, which has a url (a regular expression), a controller, and optionally a variables argument. You can have multiple variables by doing something like :

-The first two functions return a Route object or an empty string if nothing was found, which has a url::ASCIIString, a controller::ASCIIString and an array called variables.
+The first two functions return true or false depending on whether a route with a specific URL exists or not.

 ### Implementation
 That might seem a little abstract to you how to actually use it to run a julia web project, so check out PhoenixMachina's website implementation for more informations.
