+## Usage
+
+Before creating your first hook, you must initialize the module. It is advisable to add this code at the beginning of the `functions.php` file of your theme or in a `mu-plugin`.
+
+```php
+$loader = new \Dbout\Framework\Hook\HookLoader(
+    directory: get_template_directory() . '/hooks',
+);
+
+$loader->register();
+```
+
+Now you have initialized the module, you just need to create your first action in the hooks folder in your theme.
+
+```php
+use Dbout\Framework\Hook\Attributes\Action;
+use Dbout\Framework\Hook\Attributes\Filter;
+
+class MyFirstHook {
+
+    #[Action(name: 'wp_dashboard_setup', priority: 999)]
+    public function setupDashboard(): void
+    {
+        // Do something   
+    }
+    
+    #[Filter(name: 'crontrol/filtered-events', acceptedArgs: 2)]
+    public function filterEvents(array $filtered, array $events): array
+    {
+        // Do something
+        return $filtered;
+    }
+}
+```
