Custom input from Input Manager into Asset Store package?

On testing the install of my asset package to a fresh project in Unity, I got a Unity Exception saying “Input Button Use is not setup.” How do I build this as a part of the package to make sure that users have the proper keyboard inputs?

Will Goldstone comments:

"We added support for this as an option for Complete Projects category, but we know that with Sample Assets (And standard assets before them) users often import this stuff into an existing project - and we did not wish to accidentally overwrite your settings, so we went with simpler input commands for now.

Unity is revising its Input manager so at a later date all of this stuff will be easier. Anyway folks, look forward to more iterations on these assets soon."
