Diving right in!

Hello all:
I've fiddled with this game for a while, and decided to make a donation. I was really pleased to find this forum, and the ability to share designs.

One question, though: Where can I find details about the mechanics of the game, and the terminology? I tried out making a simple design, but was overwhelmed by all the parts.

BTW, my name is Daniel. I'm a 42yo former film projectionist and skiptracer, but have been disabled for 15+ years, so I've got a lot of free time on my hands. This is the type of game that could really help me recover from a stroke I had a couple of years ago. It's challenging and creative.

Thanks for any help directing me to the right place(s).
