In addition to what Loretta has said, I add the following with the sincerest of good intentions... I hope it comes across that way.
I would recommend trying to keep things in plain language that most everyone can understand. Try to follow the KISS Rule (Keep It Simple.... ) because not everyone is a geneticist. It's obvious that you and many others are very smart when it comes to Genetic Genealogy, but there are many of us out here whose eyes glaze over at the mere mention of centimorgans, double half 3rd cousins 10 times removed (what?), or other terms unique to this field.
Everyone is smart in what they know, but they are ignorant in what they don't know. As a former instructor, I know that everyone learns at a different rate, and that everyone doesn't come out of the box with the same knowledge base. If they did, everything would be easy. So please keep that in mind that everyone does not have a Doctorate in Genealogy when developing your tutorial. It's not about showing how much you know, but it's about sharing what you know with others.
