+## Livewire
+
+This package includes a Livewire compatible component that will re-render a diagram when a property on your Livewire component is updated. Here's an example of using this in a Livewire component when when you increase the 'limit', more users will be loaded and added to the diagram.
+
+```php
+
+// Your Livewire Class:
+<?php
+
+namespace App\Livewire;
+
+use App\Models\User;
+use Livewire\Component;
+
+class Mermaid extends Component
+{
+    public $limit = 2;
+
+    public $mermaid;
+
+    public function render()

+        );
+
