+## Custom validation rules
+
+### Registration
+
+Shield has the following rules for registration:
+
+```php
+[
+    'username'         => 'required|alpha_numeric_space|min_length[3]|is_unique[users.username]',
+    'email'            => 'required|valid_email|is_unique[auth_identities.secret]',
+    'password'         => 'required|strong_password',
+    'password_confirm' => 'required|matches[password]',
+];
+```
+
+If you need a different set of rules for registration, you can specify them in your `Validation` configuration (**app\Config\Validation.php**) like:
+
+```php
+//--------------------------------------------------------------------
+// Rules
+//--------------------------------------------------------------------
+public $registration = [
+    'username'         => 'required|alpha_numeric_space|min_length[3]|is_unique[users.username]',
+    'email'            => 'required|valid_email|is_unique[auth_identities.secret]',
+    'password'         => 'required|strong_password',
+    'password_confirm' => 'required|matches[password]',
+];
+```
