## Overview

AutoFlow is an Android no-code workflow editor: users create or reopen a project, choose and configure a trigger and actions, arrange and connect them on a visual canvas, and save work for later editing. The README documents undo/redo, project identity, and restoration of workflow connections. Source excerpts contain only build configuration, so component wiring beyond these documented behaviors is limited to what the README supports; app integrations are presented as selectable apps, not proven execution services.
