 ### Basic Scrolling Implementation
 
+Scroll with `ScrollHelper`, configured by `src.common.scroll_config`, and
+render one frame per `display()` call. Don't pace the scroll with
+`time.sleep()`: `update_display()` blocks on the panel's
+vsync, which is what paces a scroll. Pass the `frame_hold` that
+`scroll_config.configure()` returned to `set_scrolling_state()`, or the
+scroll runs faster than the configured speed (see
+`set_scrolling_state()` in [PLUGIN_API_REFERENCE.md](PLUGIN_API_REFERENCE.md)).
