Add explanation text for navigation

Is it worthwhile adding some text explanation somewhere about moving around and zooming? We could probably cut some of the text in the earlier intro slides or add another slide at the end.

Or do we assume the controls are intuitive enough without explanation?

ex. "use the scroll wheel to zoom in and out", "click and drag to move"

Adding text to the background could work as an alternative to adding intro slides.

Start by locating the intro slides and background text used by the navigation experience. Decide where the explanation belongs based on the existing UI, then ensure users can find guidance for zooming with the scroll wheel and moving by clicking and dragging.
