Building a project from a blank canvas to a printed document, entirely in the app - no JSON, no JavaScript. Each step links to the screen that does it; this page is the path through them, not a repeat of what's on each screen.

1. Start the project

New from the Main Menu: give it a name, a canvas size, a background color. This creates a blank base.pdf, an empty form, and drops you into the Overlay Editor.

2. Build the form

Open Form Editor and add the fields someone will fill in - text, numbers, a dropdown, whatever the document needs.

3. Design the layout

In the Overlay Editor, add blocks and connect them to those fields - a text block showing {field_id}, a logo image, a box for a panel. Position and style each one on the canvas.

4. Wire it together

A layout does nothing until process.js says to include it - Project Editor → process.js needs at least:

overlay("overlay.json");

(Already there if you started from New - a new project ships with exactly this.)

5. Fill it out and print

The app bar's Open Project button returns to Input Form for the same document - enter values, hit Submit, then Print or Save from Output Preview.

That's the whole loop. From here: Assets Overview for logos/fonts, or Advanced Authoring once you outgrow what the in-app editors alone can do (conditional content, computed values, repeating groups, tables).
