## What & why
This adds a **guided tutorial** that teaches the Twenty SDK by building
one real, useful app end to end — plus the finished app itself, ready
for the marketplace.
The app, **Document Generator**, turns reusable templates into
personalized documents using CRM data: write a template once with
`{{placeholders}}`, then generate a filled-in document for any Person or
Company from the command menu, an AI agent, or a workflow.
## Two parts
**1. The app — `packages/twenty-apps/public/document-generator`**
Each capability maps to one tutorial chapter:
- **Data:** `documentTemplate` + `document` objects, fields, and a
bidirectional relation
- **Logic:** a single `generate-document` handler exposed as an **AI
tool**, a **workflow action**, and an **HTTP POST route**; plus a public
**HTML view route**
- **UI:** two views + sidebar navigation, a **command-menu item** (on
Person selection) that opens a **React front component**
- **AI:** an agent + skill; a default application role; marketplace
metadata + logo
- **Tests:** unit tests for the template renderer + an install
integration test
**2. The tutorial —
`packages/twenty-docs/.../apps/tutorials/document-generator/`**
A six-chapter series under **Developers › Apps › Tutorial** (Overview →
Data model → Generating documents → HTTP routes → Building the UI → AI
agent → Publishing). Minimal prose, paste-ready code, inline links to
the matching reference pages, and real screenshots. Registers a new
"Tutorial" nav group and regenerates `docs.json` + the navigation
template.
## Verification
Validated against a running Twenty instance (`twenty-app-dev` on
`:2020`):
- `twenty dev --once` installs cleanly (28 metadata objects created)
- Generated a real document from a Person — placeholders resolved (name,
job title, `company.name`, email), zero missing tokens
- Command menu → front component → generate flow works in the UI
- Public HTML view route renders the document
- App gates green: `yarn lint` (0/0), `yarn typecheck`, `yarn test:unit`
(7/7)
All screenshots in the tutorial are captured from this run.
## Notes
- Left out per-app CI workflows (`.github/workflows`) to keep scope
tight — happy to add them if wanted.
