+#### Model Hooks
+
+If you need additional information on your model from sources that are not handled by default, you can hook in to the
+ generation process with model hooks to add extra information on the fly.
+ Simply create a class that implements `ModelHookInterface` and add it to the `model_hooks` array in the config:
+ 
+ ```php
+'model_hooks' => [
+    MyCustomHook::class,
+],
+```
+
+The `run` method will be called during generation for every model and receives the current running `ModelsCommand` and the current `Model`, e.g.:
+
+```php
+class MyCustomHook implements ModelHookInterface
+{
+    public function run(ModelsCommand $command, Model $model): void
+    {
+        if (! $model instanceof MyModel) {
+            return;
+        }
+
+        $command->setProperty('custom', 'string', true, false, 'My custom property');
+    }
+}
+```
+
+```php
+/**
+ * MyModel
+ *
+ * @property integer $id
+ * @property-read string $custom
