Is there a sample or tutorial that jumps right into typical examples of what's different or special about it? I tried to find such, but the docs get lost in syntax details and other minutia. I want the ADHD-meat-and-potatoes tutorial. Maybe that's asking too much, but I did it anyhow, as any ADHDer would.
