-This package contains a lot of 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']);
-// result: "lorem"
+```json
+"repositories": [

+# Meritoo Common Library
+
+Common and useful classes, methods, exceptions etc.
+
+# Base test case (with common methods and data providers)
+
+Located here: `Meritoo\Common\Test\Base\BaseTestCase`.
+
+##### Usage
+
+1. Just extend the `BaseTestCase` class or implement `Meritoo\Common\Traits\Test\Base\BaseTestCaseTrait` trait.
+2. Use one of available data providers, e.g. `@dataProvider provideEmptyValue`, or asserts,
+   e.g. `static::assertMethodVisibility($method, $visibilityType);`
+
+##### Examples
+
+```php
+class DateTest extends BaseTestCase
+{
+    /**
+     * @param mixed $value Empty value, e.g. ""
+     * @dataProvider provideEmptyValue
+     */
+    public function testGetDateTimeEmptyValue($value)
+    {
+        self::assertFalse(Date::getDateTime($value));
+    }
+
+	(...)
+}
+```
+
+```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));
+    }
+
+	(...)
+}

+# Meritoo Common Library
+
+Common and useful classes, methods, exceptions etc.
+
+# BaseCollection
+
+### Namespace
+
+`Meritoo\Common\Collection\BaseCollection`
+
+### Info
+
+It's a set of some elements with the same type, 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($element)` - removes given element
+
+### Implementation
+
+You have to implement:
+
+```php
+abstract protected function isValidType($element): bool;
+```
+
+This method verifies 1 element before it will be added to collection. Returns information if the element has valid,
+expected type.
+
+Example (from `Meritoo\Common\Collection\Templates` class):
+
+```php
+protected function isValidType($element): bool
+{
+    return $element instanceof Template;
+}
+```
+
+### Methods to overwrite
+
+You can, if you wish, overwrite these methods:
+
+1. To prepare elements used to initialize the collection in your own way:
+
+    ```php
+    protected function prepareElements(array $elements): array
+    ```
+
+2. To validate type of elements in your own way:
+
+    ```php
+    protected function getElementsWithValidType(array $elements): array
+    ```
+
+### Examples of usage
+
+```php
+use Meritoo\Common\Collection\StringCollection;
+
+$emptyCollection = new StringCollection();
+var_dump($emptyCollection->isEmpty()); // bool(true)
+
+$elements = [
+    'lorem',
+    'ipsum',
+    123 => 'dolor',
+    345 => 'sit',
+];
+
+$simpleCollection = new StringCollection($elements);
+var_dump($simpleCollection->has('dolor')); // bool(true)

+
+### 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.

+# Exceptions
+
+### 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
+{
+    /**
+     * Creates exception
+     *
+     * @param string $unknownType Unknown and simple type
+     * @return UnknownSimpleTypeException
+     */
+    public static function createException($unknownType)
+    {
+        /* @var UnknownSimpleTypeException $exception */
+        $exception = parent::create($unknownType, new SimpleType(), 'my simple type of something');

-    Attention 1.
-    To use Symfony2 standards to check coding you have to:
-    copy, symlink or check out repo to a folder called Symfony2 inside the phpcs Standards directory.
-
-    Example:
-    $ pear config-show | grep php_dir

-    $ git clone git://github.com/opensky/Symfony2-coding-standard.git Symfony2

-    Attention 2.
-    PSR2 standard is used instead of Symfony2 standard, because after installation squizlabs/php_codesniffer package
-    via Composer the Symfony2 standard is not included / available in this package. In this case the PHP Coding
-    Standards Fixer (http://cs.sensiolabs.org) is used.
