+
+### Namespace
+
+`Meritoo\Common\Collection\Templates`
+
+### Info
+
+Collection/storage of templates, instance of `Meritoo\Common\ValueObject\Template` class.
+
+##### New instance
+
+New instance can be created using:
+
+1. Constructor:
+
+	```php
+    new Templates([
+    	'first' => new Template('First name: %first_name%'),
+        'last'  => new Template('Last name: %last_name%'),
+    ]);
+    ```
+
+2. Static method `fromArray(array $templates)` - creates and returns the collection from given array
+
+	```php
+	Templates::fromArray([
+    	'first' => 'First name: %first_name%',
+        'last'  => 'Last name: %last_name%',
+    ]);
+	```
+
+##### Methods
+
+Has all methods of parent class `Meritoo\Common\Collection\Collection` + `findTemplate(string $index)` method that finds and returns template with given index.
+
+Example of usage:
+
+```php
+$templates = new Templates([
+	'first' => new Template('First name: %first_name%'),
+    'last'  => new Template('Last name: %last_name%'),
+]);
+
+$template = $templates->findTemplate('first'); // new Template('First name: %first_name%')
+```
+
+Throws an `Meritoo\Common\Exception\ValueObject\Template\TemplateNotFoundException` exception if template with given index was not found.
