How Nendo works today and how to use it, written for somebody who has not seen it before.
Start
What Nendo is and how to open your first file.
Use
Screens, calculations, agents, custom views and your data.
Screens
Every kind of screen a Nendo file can hold, what each one reads, where its parts go, and its limits.
Calculations and actions
Calculated fields, reusable functions, automatic actions and triggers, their limits, and why a file with triggers needs approval on each computer.
Agents
Connect Claude Code or Codex to an open Nendo file, choose what it may do, and review what it proposes.
Files and data
What a .nendo file holds and its limits, CSV import and export, history and undo, the four kinds of copy, and what you can still do when a file opens read-only or needs recovery.
Custom views
What a custom view is, how its code travels in the file and runs inside Nendo, what it can reach, how to switch views off, and how to build your own.
Project
Where Nendo is now and where it could go.
Contributing? The repository keeps its engineering record under docs/: the architecture, the behavioural contracts, the architecture decisions and the roadmap. Those documents describe how Nendo was built and are the authority for changing it.
