The recommended way to install this extension is via Composer.

## Installation via Composer {#installation-composer}

```bash
composer require netresearch/contexts
```

After installation, activate the extension in the TYPO3 Extension Manager or
via CLI:

```bash
vendor/bin/typo3 extension:activate contexts
```

## Site Set Configuration (TYPO3 v13+) {#installation-site-set}

<!-- TODO: no Markdown rendering for "versionadded" -->

Site Sets support for TYPO3 v13.

For TYPO3 v13 and later, you can include the Contexts site set in your site
configuration:

1.  Go to **Site Management > Sites**
1.  Edit your site configuration
1.  In the **Sets** tab, add "Contexts - Multi-channel content visibility"

Alternatively, add it to your site's `config/sites/<identifier>/config.yaml`:

```yaml
dependencies:
  - netresearch/contexts
```

## Database Updates {#installation-database}

After installation, run the database analyzer to create required tables:

```bash
vendor/bin/typo3 database:updateschema
```

Or use the **Admin Tools > Maintenance > Analyze Database Structure**
module in the TYPO3 backend.

## Verification {#installation-verification}

After installation, you should see:

1.  A new "Contexts" module in the backend (under Admin Tools)
1.  "Context visibility" options in page and content element properties
1.  Database tables: `tx_contexts_contexts`, `tx_contexts_settings`
