Start learning follows Home, all ten systems and Profile using the supplied app screenshots. The guide buttons move between lessons; account actions happen in your own app.

1. Read the current instruction and What to notice. The highlighted area shows where to look on the full screen. Its steady detail appears alongside it.
2. Use Next and Back to move through the whole course, including the next branch or chapter. Chapters lets you revisit a particular system without leaving the course.
3. Select an image area or open Adjust detail to move the detail with buttons. Open full image lets you inspect the complete captured screen.

Resume learning returns to the course screenshot you most recently opened in this browser tab. The address preserves an exact step for reload, copying and browser Back/Forward. Course, task and reference positions are separate.

Screen reference and Task walkthroughs remain available for a specific question. Task walkthroughs can include labelled fictional examples and optional Replay. Left/Right arrow keys advance when focus is outside controls. Opening a dialog or leaving a route stops Replay.

If an image cannot load, its screen description appears below it. Dark bars and [Hidden] conceal protected content.

Admin has its own guide and controls. About the sources explains evidence limits.
