Basics, hmm.
1. Dig down stairs, dig up stairs, dig rooms.
or
1. Channel down, dig rooms.
I think my problem is I like flat embarks, so I don't immediately dig a tunnel and get a roofed entry.
So, above ground construction is more advanced that basic. Got it.
Machinery would be advanced too.
Idea. I think a jump to early Wood Burner, Smelter, Metalsmith's Forge and make military would be a good stand alone "save" tutorial. More intermediate that advanced maybe? This can even cover creating militia commander, uniform setup, set barracks, and training.
With plenty 100 booze, 20 meat, the rest of the embark can focus on ores (bronze), bit coals, and ready made backpacks and waterskins.
Another idea is embark with 1 hunter, 1 marksdwarf, 1 butcher/tanner/leather worker. Then focus on equipment making from bones and leather. This should help demonstrate the behavior of hunter, and a military to order to kill the hunter's targets too, and setup archery range as well.
My favorite idea is hemp farming, but that depends on a biome with hemp plants read for gathering. Then build above ground farm, below a roofed building. Then show case the usefulness of hemp: oil, soap, thread, clothing, and papers.
