# Installation
### Cloud
The fastest way to get started. Sign up at [twenty.com](https://twenty.com) and spin up a workspace in under a minute, with no infrastructure to manage and always up to date.
### Build an app
Scaffold a new app with the Twenty CLI:
```bash
npx create-twenty-app my-app
```
Define objects, fields, and views as code:
```ts
import { defineObject, FieldType } from 'twenty-sdk/define';
export default defineObject({
nameSingular: 'deal',
namePlural: 'deals',
labelSingular: 'Deal',
labelPlural: 'Deals',
fields: [
{ name: 'name', label: 'Name', type: FieldType.TEXT },
{ name: 'amount', label: 'Amount', type: FieldType.CURRENCY },
{ name: 'closeDate', label: 'Close Date', type: FieldType.DATE_TIME },
],
});
```
Then ship it to your workspace:
```bash
npx twenty deploy
```
See the [app development guide](https://docs.twenty.com/developers/extend/apps/getting-started) for objects, views, agents, and logic functions.
### Self-hosting
Run Twenty on your own infrastructure with [Docker Compose](https://docs.twenty.com/developers/self-host/capabilities/docker-compose), or contribute locally via the [local setup guide](https://docs.twenty.com/developers/contribute/capabilities/local-setup).
