-use Meritoo\Common\Utilities\Arrays;
-
-$firstElement = Arrays::getFirstElement(['lorem' 'ipsum']);
-// result: "lorem"
+```bash
+composer require meritoo/common-library

+# 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

+
+# Tests
+
+### Prerequisites
+
+Install required packages by running command: `docker-compose run composer install`.
+
+### Running tests
+
+#### Simply & quick, without code coverage
+
+Tests are running using Docker and `php-cli` service defined in `docker-compose.yml`. Example:
+
+```bash
+docker-compose exec php-cli phpunit --no-coverage
+```
+
+You can also run them in container. In this case you have to run 2 commands:
+1. Enter container:
+
+    ```bash
+	docker-compose exec php-cli bash
+    ```
+
+2. Run tests:
+
+    ```bash
+    phpunit --no-coverage
+    ```
+
+#### With code coverage
+
+```bash
+docker-compose exec php-cli phpunit
+```
+
+# Other
+
+Rebuild project and run tests by running command:
+
+```bash
+docker-compose exec php-cli phing
+```

+# 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"
+```
