Does anyone have any experience deploying apps with dependencies using PSADT v4?

I'm new to using PSADT. I've been going through the documentation for the v4 but I can't seem to find documentation on how to properly add dependency applications to the invoke script.

Do I add the dependency installers to the "Files" or "Support Files" folder?

Do I use the Execute-Process -Path command to run the dependencies? And do I add that to the pre-install section or the install section?

Any help is greatly appreciated.
