-# Static methods
-
-This package contains a lot of class with static methods, so usage is not so complicated. Just run the static method who would you like to use. Example:
-
-```php
-use Meritoo\Common\Utilities\Arrays;
-
-$firstElement = Arrays::getFirstElement(['lorem', 'ipsum']);
-var_dump($firstElement); // string(5) "lorem"
-```
-
-# Base test case with common methods and data providers
-
-Located here: `Meritoo\Common\Test\Base\BaseTestCase`. Just extend the `BaseTestCase` class and use it like in `Meritoo\Common\Test\Utilities\DateTest` class:
-
-```php
-class DateTest extends BaseTestCase
-{
-    /**
-     * @param mixed $value Empty value, e.g. ""
-     * @dataProvider provideEmptyValue
-     */
-    public function testGetDateTimeEmptyValue($value)
-    {
-        self::assertFalse(Date::getDateTime($value));
-    }
-
-	(...)
-}
-```
-
-or in `Meritoo\Common\Test\Utilities\MimeTypesTest` class:
-
-```php
-class MimeTypesTest extends BaseTestCase
-{
-	(...)
-
-    /**
-     * @param bool $mimeType The mime type, e.g. "video/mpeg"
-     * @dataProvider provideBooleanValue
-     */
-    public function testGetExtensionBooleanMimeType($mimeType)
-    {
-        self::assertEquals('', MimeTypes::getExtension($mimeType));
-    }
-
-	(...)
-}
-```
-
-# Collection of elements
-
-Located here: `Meritoo\Common\Collection\Collection`. It's a set of some elements, e.g. objects. It's iterable and countable. Provides very useful methods. Some of them:
-- `getFirst()` - returns the first element in the collection
-- `getLast()` - returns the last element in the collection
-- `isEmpty()` - returns information if collection is empty
-- `add($element, $index = null)` - adds given element (at the end of collection)
-- `addMultiple($elements, $useIndexes = false)` - adds given elements (at the end of collection)
-- `prepend($element)` - prepends given element (adds given element at the beginning of collection)
-- `remove($element)` - removes given element
-
-Examples of usage below.
-
-### An empty collection
-
-```php
-use Meritoo\Common\Collection\Collection;
-
-$emptyCollection = new Collection();
-var_dump($emptyCollection->isEmpty()); // bool(true)
-```
-
-### Simple collection
-
-```php
-use Meritoo\Common\Collection\Collection;
-
-$elements = [
-    'lorem',
-    'ipsum',
-    123 => 'dolor',
-    345 => 'sit',
-];
-
-$simpleCollection = new Collection($elements);
-var_dump($simpleCollection->has('dolor')); // bool(true)
-```
