## Setup

<Steps>
  <Step title="Install">
    <CodeGroup>
      ```bash npm theme={null}
      npm install corsair @corsair-dev/studiobyai21labs
      ```

      ```bash yarn theme={null}
      yarn add corsair @corsair-dev/studiobyai21labs
      ```

      ```bash pnpm theme={null}
      pnpm install corsair @corsair-dev/studiobyai21labs
      ```

      ```bash bun theme={null}
      bun add corsair @corsair-dev/studiobyai21labs
      ```
    </CodeGroup>
  </Step>

  <Step title="Add the plugin">
    ```ts corsair.ts theme={null}
    import Database from 'better-sqlite3';
    import { createCorsair } from 'corsair';
    import { studiobyai21labs } from '@corsair-dev/studiobyai21labs';

    export const corsair = createCorsair({
    	plugins: [
    		studiobyai21labs(),
    	],
    	database: new Database('corsair.db'),
    	kek: process.env.CORSAIR_KEK!,
    	hub: {
    		projectApiKey: process.env.CORSAIR_DEV_API_KEY!,
    		signingSecret: process.env.CORSAIR_DEV_SIGNING_SECRET!,
    	},
    });
    ```

    Multi-tenancy is the default — scope calls with `corsair.withTenant(id)`. See [Quick start](/quick-start) for KEK + Hub keys, and [Multi-tenancy](/concepts/multi-tenancy) for account isolation.
  </Step>

  <Step title="Choose authentication">
    <Tabs>
      <Tab title="API Key (Recommended)">
        No setup required yet. When you make your first request as a tenant, Corsair prompts for the API key.

        ```ts theme={null}
        studiobyai21labs()
        ```

        More: [API Key](/concepts/api-key)
      </Tab>
    </Tabs>
  </Step>

  <Step title="Connect a tenant">
    Mint a connect link and send the tenant to it. Hub hosts the page and delivers the result to your app — see [Connect / OAuth](/management/connect).

    ```ts theme={null}
    const { connectUrl } = await corsair.manage.connect.createLink({
    	plugin: 'studiobyai21labs',
    	tenantId: 'acme',
    });
    // redirect the user's browser to connectUrl
    ```
  </Step>
</Steps>

## Example API calls

**`library.download`**

```ts theme={null}
const tenant = corsair.withTenant('acme');
await tenant.studiobyai21labs.api.library.download({});
```

**`chat.completions`**

```ts theme={null}
const tenant = corsair.withTenant('acme');
await tenant.studiobyai21labs.api.chat.completions({});
```
