+# Development
 
-## Static methods
+More information [you can find here](docs/Development.md)
-
-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)
-```
 
 Enjoy!

+# 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',

+

+
+# Getting started
+
+1. Build, create and start Docker's containers by running command:
+
+    ```bash
+    docker-compose up -d
+    ```
+
+2. Install packages by running command:
+
+    ```bash
+    docker-compose run composer install
+    ```
+
+> [What is Docker?](https://www.docker.com/what-docker)
+
+# Composer
+
+Available as `composer` service. You can run any Composer's command using the `composer` service:
+
+```bash
+docker-compose run composer <command>
+```
+
+Examples below.
+
+##### Install packages
+
+```bash
+docker-compose run composer install
+```
+
+##### Update packages
+
+```bash
+docker-compose run composer update
+```
+
+##### Add package
+
+```bash
+docker-compose run composer require <vendor>/<package>
+```
+
+##### Remove package
+
+```bash
+docker-compose run composer remove <vendor>/<package>
+```

+
+# 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` service defined in `docker-compose.yml`. Example:
+
+```bash
+docker-compose exec php 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 bash
+    ```
+
+2. Run tests:
+
+    ```bash
+    phpunit --no-coverage
+    ```
+
+#### With code coverage
+
+```bash
+docker-compose exec php phpunit
+```
+
+# Other
+
+Rebuild project and run tests by running command:
+
+```bash
+docker-compose exec php phing

+
+### Create instance of exception
+
+This package contains a lot of exceptions. Each of them contains static method `create()` with proper arguments that is used to create instance of the exception. Example:
+
+```php
+use Meritoo\Common\Exception\Bundle\IncorrectBundleNameException;
+throw IncorrectBundleNameException::create('RisusIpsum');
+```
+
+### Base exception for unknown type of something
+
+##### Short description
+
+It's a `Meritoo\Common\Exception\Base\UnknownTypeException` class. Related to `Meritoo\Common\Type\Base\BaseType` class that represents type of something, e.g. type of button, order.
+
+##### Usage
+
+You can extend `Meritoo\Common\Exception\Base\UnknownTypeException` class and create your own static method, e.g. `createException()`, which will be used create instance of the exception. Inside the `createException()` method you can call `parent::create()` method.
+
+##### Example
+
+```php
+<?php
+
+namespace Your\Package\Exception\Type;
+
+use Meritoo\Common\Exception\Base\UnknownTypeException;
+use Your\Package\Type\SimpleType;
+
+class UnknownSimpleTypeException extends UnknownTypeException

+        $exception = parent::create($unknownType, new SimpleType(), 'my simple type of something');
