-[![Total Downloads](https://poser.pugx.org/ergebnis/php-cs-fixer-config/downloads)](https://packagist.org/packages/ergebnis/php-cs-fixer-config)
-
-Provides a configuration factory and multiple rule sets for [`friendsofphp/php-cs-fixer`](http://github.com/FriendsOfPHP/PHP-CS-Fixer).
-
-## Installation
-
-Run
-
-```sh
-$ composer require --dev ergebnis/php-cs-fixer-config
-```
-
-## Usage
-
-### Configuration
-
-Pick one of the rule sets:
-
-* [`Ergebnis\PhpCsFixer\RuleSet\Laravel6`](src/RuleSet/Laravel6.php)
-* [`Ergebnis\PhpCsFixer\RuleSet\Php71`](src/RuleSet/Php71.php)
-* [`Ergebnis\PhpCsFixer\RuleSet\Php73`](src/RuleSet/Php73.php)
-
-Create a configuration file `.php_cs` in the root of your project:
-
-```php
-<?php
-
-use Ergebnis\PhpCsFixer\Config;
-
-$config = Config\Factory::fromRuleSet(new Config\RuleSet\Php71());
-
-$config->getFinder()->in(__DIR__);
-$config->setCacheFile(__DIR__ . '/.build/php-cs-fixer/php_cs.cache');
-
-return $config;
-```
-
-### Git
-
-All configuration examples use the caching feature, and if you want to use it as well, you should add the cache directory to `.gitignore`:
-
-```diff
-+ /.build/
- /vendor/
-```
-
-:bulb: Personally, I prefer to use a `.build` directory for storing build artifacts.
-
-### Configuration with header
-
-:bulb: Optionally specify a header:
-
-```diff
- <?php
-
- use Ergebnis\PhpCsFixer\Config;
-
-+$header = <<<EOF
-+Copyright (c) 2019 Andreas Möller
-+
-+For the full copyright and license information, please view
-+the LICENSE file that was distributed with this source code.
-+
-+@see https://github.com/ergebnis/php-cs-fixer-config
-+EOF;
-
--$config = Config\Factory::fromRuleSet(new Config\RuleSet\Php71());
-+$config = Config\Factory::fromRuleSet(new Config\RuleSet\Php71($header));
-
- $config->getFinder()->in(__DIR__);
- $config->setCacheFile(__DIR__ . '/.build/php-cs-fixer/php_cs.cache');
-
- return $config;
-```
-
-This will enable and configure the [`HeaderCommentFixer`](https://github.com/FriendsOfPHP/PHP-CS-Fixer/blob/v2.1.1/src/Fixer/Comment/HeaderCommentFixer.php), so that
-file headers will be added to PHP files, for example:
-
-```php
-<?php
-
-/**
- * Copyright (c) 2019 Andreas Möller
- *
- * For the full copyright and license information, please view
- * the LICENSE file that was distributed with this source code.
- *
- * @see https://github.com/ergebnis/php-cs-fixer-config
- */
-```
-
-### Configuration with override rules
-
-:bulb: Optionally override rules from a rule set by passing in an array of rules to be merged in:
-
-```diff
- <?php
-
- use Ergebnis\PhpCsFixer\Config;
-
--$config = Config\Factory::fromRuleSet(new Config\RuleSet\Php71());
-+$config = Config\Factory::fromRuleSet(new Config\RuleSet\Php71(), [
-+    'mb_str_functions' => false,
-+    'strict_comparison' => false,
-+]);
-
- $config->getFinder()->in(__DIR__);
- $config->setCacheFile(__DIR__ . '/.build/php-cs-fixer/php_cs.cache');
-
- return $config;
-```
-
-### Makefile
-
-If you like [`Makefile`](https://www.gnu.org/software/make/manual/make.html#Introduction)s, create a `Makefile` with a `coding-standards` target:
-
-```diff
-+.PHONY: coding-standards
-+coding-standards: vendor
-+	 mkdir -p .build/php-cs-fixer
-+    vendor/bin/php-cs-fixer fix --config=.php_cs --diff --verbose
-
- vendor: composer.json composer.lock
-     composer validate
-     composer install
-```
-
-Run
-
-```
-$ make coding-standards
-```
-
-to automatically fix coding standard violations.
-
-### Composer script
-
-If you like [`composer` scripts](https://getcomposer.org/doc/articles/scripts.md), add a `coding-standards` script to `composer.json`:
-
-```diff
- {
-   "name": "foo/bar",
-   "require": {
-     "php": "^7.2",
-   },
-   "require-dev": {
-     "ergebnis/php-cs-fixer-config": "~1.0.0"
-+  },
-+  "scripts": {
-+    "coding-standards": [
-+      "mkdir -p .build/php-cs-fixer",
-+      "php-cs-fixer fix --diff --diff-format=udiff --verbose"
-+    ]
-   }
- }
-```
-
-Run
-
-```
-$ composer coding-standards
-```
-
-to automatically fix coding standard violations.
-
-### GitHub Actions
-
-If you like [GitHub Actions](https://github.com/features/actions), add a `coding-standards` job to your workflow:
-
-```diff

-   push:
-     branches:
