Before we start the project, we have to prepare the material in our mobile device so that we can access it quickly:

1. The first thing we need to do is register on their web page (http://creativitic.es/augmentedclass/beta/) and download the Android app at https://play.google.com/store/apps/details?id=com.AugmentedClass.AClass&hl=es_419. The app allows us demo access without us having to log in, but it has more restrictions for projects than it does with registered access.
2. Now, on your phone or tablet, create a folder called AClass in the root folder and copy the model file, gearbox_worm.glb, and the markers, gearbox_worm.jpg and component_desc.jpg, into it. Creating a folder isn't required, but it will make using and searching for content from the app easier.

Now, we are ready to start the app.
