# Installation {#installation}

## Installation via Composer {#installation-composer}

The recommended way to install ai3-alttext is via Composer:

**Install the extension**

```bash
composer require wegewerk/ai3_alttext
```

This will also pull in [`wegewerk/ai3_core`](https://packagist.org/packages/wegewerk/ai3_core) automatically.

## Activate the extension {#installation-activate}

After installation, activate the extension in the TYPO3 backend:

1.  Open **Admin Tools > Extensions**
1.  Find **Ai3 Alt Text** in the list
1.  Click the **Activate** button

> [!NOTE]
> When using Composer-based TYPO3 installations the extension is
> activated automatically. No manual activation is required.

## Database update {#installation-database}

No additional database tables are created by this extension. All
generation task data is stored via [`wegewerk/ai3_core`](https://packagist.org/packages/wegewerk/ai3_core).

Run the database analyser after installation to ensure the core tables
are up to date:
