+# Type
+
+Validates that a value is of a specific type.
+
+If an array with multiple types is provided, it will validate if the value is of at least one of the given types.
+For example, if `['alpha', 'numeric']` is provided, it will validate if the value is of type `alpha` or of type `numeric`.
+
+```php
+Type(
+    string|array $constraint,
+    string $message = 'The "{{ name }}" value should be of type "{{ constraint }}", "{{ value }}" given.'
+);
+```
+
+## Basic Usage
+
+```php
+// Single type
+Validator::type('string')->validate('green'); // true
+Validator::type('alphanumeric')->validate('gr33n'); // true
+
+// Multiple types
+// Validates if value is of at least one of the provided types
+Validator::type(['alpha', 'numeric'])->validate('green'); // true (alpha)
+Validator::type(['alpha', 'numeric'])->validate('33'); // true (numeric)
+Validator::type(['alpha', 'numeric'])->validate('gr33n'); // false (not alpha nor numeric)
+
+// Class or interface type
+Validator::type(\DateTime::class)->validate(new \DateTime()); // true
+Validator::type(\DateTimeInterface::class)->validate(new \DateTime()); // true
+```
+
+> **Note**
+> An `UnexpectedValueException` will be thrown when a constraint type, class or interface is invalid.
+
+## Options
+
+### `constraint`
+
+type: `string`|`array` `required`
+
+Type(s) to validate the input value type. 
+Can validate instances of classes and interfaces.
+
+If an array with multiple types is provided, it will validate if the value is of at least one of the given types.
+For example, if `['alpha', 'numeric']` is provided, it will validate if the value is of type `alpha` or of type `numeric`.
