Documentation?

[GKL]

Is there any documentation for this software other than what is in this forum?

I've generally been able to find answers to questions on here but some still persist, such as:

What does the Update button do and when do I need to use it?

Thanks

There was documentation but that was lost. The update function in the config is for when you add new media or if you want to point to a different drive to add media.
