Gallery of Example Models!

This gallery will hold example models as we build them. To learn about installing umx, or take a basic tutorial, start at the [home page](

note: This page expresses the goal for umx’s coverage of core copy-and-paste model templates. Goal deadline to have it completed by end 2021.
