# Very important! 
    * AS FOR NOW THE PLUGIN DOES NOT SUPPORT IN APP TRAINING OF THE IMGDB FILE
    * The IMGDB File has to be PRETRAINED and saved in a Temp Directory before the ArCoreView is created 
    * The IMGDB File name hast to be image_database.imgdb
     * you can find a pretained imgdb file under example/assets. The images that the imgdb file is trained with are found under example/assets/tester_images
    * for more info about ARCore imgdb files see : https://developers.google.com/ar/develop/c/augmented-images/arcoreimg
