Choose Start with the demo codebase. The demo canvas opens. Bring your codebase takes you to Codebase Setup instead; see Connect a GitHub repository.

You now see the demo canvas, Welcome to Modeinspect!. It is a guided tour laid out top to bottom. It starts with a welcome and a frame to iterate on with the agent, then a Portal running the demo shop, then components, Build Mode and sharing. Press ⇧ 1 to fit the whole tour on screen, or ⇧ 2 to zoom to what you selected. Hold Space to pan. Canvas controls and keyboard shortcuts lists the rest.

Your first time in Build Mode
The first time you open Build Mode, on any canvas, two cards show you around. Each one shows once.
Your building agent sits above the build chat's message box, and the stage dims until you act. Send a message or click Got it.
After the agent's first reply, Bring your app back to the canvas opens under Capture selection in the address bar. Click Capture to pick a part of the page, or Maybe later. The toast for that first capture, Capture added to canvas, stays until you click it or leave Build Mode.
