Nine groups. These two teach, in order.

## The shortest version

You describe a table in a file. The generator reads that file and writes a typed
app object, five REST routes and a client that carries the same types. Change the
description and all of them move together, because none of it was written twice.

```ts title="src/questpie/server/collections/news.ts"
import { collection } from "#questpie/factories";

export const news = collection("news").fields(({ f }) => ({
	title: f.text(255).label("Title").required(),
	isPublished: f.boolean().default(false),
}));
```

**[What QUESTPIE is](/docs/learn)** takes that file apart: what the core builds
from it, what the modules add, and which package each piece comes from.
