they really arent...
1. Download/extract files
2. Allow the app to create a folder on your device (by running app inside the files)
3. Move neccessary files (that you downloaded) to the folder you just created.
The actual instructions even tell you the names and folder locations for these.
I hope that this helps you understand what you are doing because once you understand it, you shouldn't have many/any issues with this or any other game in the future. The only variables (for the most part) that MAY change are the folder locations and what you need to copy.
