-## Features
-[feature highlights]
+This widget let's you set up the files to load a Unity file in a Mendix app using WebGL.
+It uses https://github.com/jeffreylanters/react-unity-webgl for this.
 
 ## Usage
-[step by step instructions]
+The widget needs to load 4 specific files that come with a Unity file.
+For this, it needs four filedocument public URL's to the files.
 
-## Demo project
-[link to sandbox]
+In order to get a FileDocument's URL, use the GetGUID call from the Community Commons which is available on the Mendix Marketplace.
+You can then construct the URL like this: '/file?guid='+$GUID
