+## Use as library
+
+Alltube can also be used as a library to extract a video URL from a webpage.
+
+You can install it with:
+
+```bash
+composer require rudloff/alltube
+```
+
+You can then use it in your PHP code:
+
+```php
+use Alltube\Config;
+use Alltube\VideoDownload;
+
+require_once __DIR__.'/vendor/autoload.php';
+
+$downloader = new VideoDownload(
+    new Config(
+        [
+            'youtubedl' => '/usr/local/bin/youtube-dl',
+        ]
+    )
+);
+
+$downloader->getURL('https://www.youtube.com/watch?v=dQw4w9WgXcQ');
+```
+
+The library documentation is available on [alltube.surge.sh](https://alltube.surge.sh/classes/Alltube.VideoDownload.html).
