Wikitude

I am currently following the cordova plugin documentation on the wikitude website and when I run the specific code in the  "Loading your augmented reality" section, I get an error saying a file is missing. In my code it says set "arExperienceUrl: 'directory" but I am not sure where to get the experience to load in the app. I am very new to this and would like someone to help me find this "experience" so I can test my image recognition for the surf board image.
