+### Database Support
+
+Sometimes you might want to store the cart in the database so that the cart can be retrieved even after the user logs out or closes the browser.
+
+You may also find yourself wanting to add cart timeouts and support for multiple computers.
+
+To get started, you'll need to create a new model for your Cart, the package requires only 3 columns, but you're free to extend this as you wish:
+
+```php
+$table->string('session_id');
+$table->text('items');
+$table->text('conditions');
+```
+
+Then add some json casts to your model:
+
+```php
+protected $casts = [
+    'items' => 'array',
+    'conditions' => 'array',
+];
+```

 ## 🫡 Credits
 
 This package was orignally created by [darryldecode](https://github.com/darryldecode) but has since seen almost no updates. I have decided to take the old package and transform it into a new package with new features and updates.
