+## All
+
+Validates every element of an `array` with a set of rules.
+
+## Basic Usage
+
+```php
+Validator::all([Validator::greatarThan(1), Validator::lessThan(10)])->validate([4, 5, 6]); // true
+Validator::all([Validator::greaterThan(1)->lessThan(10)])->validate([4, 5, 6]); // true
+
+Validator::all([Validator::greatarThan(1), Validator::lessThan(10)])->validate([4, 5, 20]); // false
+```
+
+> **Note**
+> An `UnexpectedValueException` will be thrown if a `constraints` element does not implement a `RuleInterface`.
+
+> **Note**
+> An `UnexpectedValueException` will be thrown when value to be validated is not an `array`.
+
+## Options
+
+### `constraints`
+
+type: `array` `required`
+
+Collection of rules, or validators, to validate each element of an `array`. 
+Each element must implement a `RuleInterface`, so it is possible to use a single rule or a full validator set of rules.
+
+### `message`
+
+type: `string` default: `At "{{ key }}": {{ message }}`
+
+Message that will be shown if at least one element of an array is invalid according to the given constraints.
+Check the [Custom Messages]() section for more information.
+
+```php
+Validator::all([Validator::notBlank()])->assert([1, 2, ''], 'Test'); 
+// Throws: At "2": The "Test" value should not be blank, "" given.
+```
+
+The following parameters are available:
+
+| Parameter       | Description                           |
+|-----------------|---------------------------------------|
+| `{{ value }}`   | The current invalid array value       |
+| `{{ name }}`    | Name of the value being validated     |
+| `{{ key }}`     | The array key of the invalid value    |
+| `{{ message }}` | The rule message of the invalid value |
