 ## Installation

+#### Strict validation
+
+Now you can strictly validate the exact profane word in the content.
+
+```php
+<?php
+// ...
+class MyController extends Controller
+{
+    public function store(Request $request)
+    {
+        $this->validate($request, [
+            'username' => 'required|strictly_profane:es,en'
+        ]);
+
+        // ...
+    }
+}
+```
+
+This fixes known issues when you get a error in validation for words like `class` or `analysis`, as they include `ass` and `anal` respectively, but fails the validation for content like `sucker69`.
