- concept-driven presentation vs data-driven presentation
- focusing on the goal first, hierarchical layering of concepts to get there
- separately, focus on getting examples fixed to lift support burden
- action: subset ~10 notebooks and drop into example jupyterbook format for demo and "exemplary workflow"
