Event Calendar 3 how to

I may just be a dummy, but I have attempted to run the EventCalendar3 plugin on my wp site and I just can’t seem to get it to work. The brief instructions that I was able to locate on the plugin’s website, as well as the wp docs did not seem clear to me and maybe that’s because I am pretty new to all this. I did what I understood the instructions to be, but I still do not see it anywhere. Is it pretty straightforward and I am just missing something, or is there a place that gives a little more step-by-step instructions for it? Also, it mentioned “subscribing” to ical. What does that mean?
