What next, after reading the Getting Started with Mini vMac page :
ROM location
You can avoid having to tell Mini vMac where the ROM image file is on every launch by putting the file in one of the places that Mini vMac looks for it. The simplest place is in the folder containing the Mini vMac application. The ROM image file needs to be named “vMac.ROM”. See the ROM section of the Emulated Hardware Reference for the full list of places.

These are How-To guides that go beyond the Getting Started guide.
Read the documentation
The Control page, about the user interface, and the emulated Hardware reference are rather dense, but have a lot of useful information.
Get Macintosh Software
The Software pages have hundreds of programs that will run on a Macintosh Plus, repackaged into the zipped disk image format that is convenient for use with Mini vMac.
The Mini vMac Extras are a collection of software made to be used with Mini vMac.
To use your own programs from other sources with Mini vMac, you will first need to get it into a disk image. This can be done with the ImportFl utility.
Learn about Macintosh
One source of general Macintosh information is old books. They usually can be found used quite cheaply. My Books about Macintosh 680x0 index lists many, including Amazon links.
