-Set of PHP-CS-Fixer rules used in the development of Ely.by PHP projects
+
+Set of PHP-CS-Fixer rules used in development of Ely.by PHP projects. It's suited for PHP 7.1 and above.
+You can use it as a ready-made set of rules or [just some of them](#using-our-fixers).
+
+## Installation
+
+First of all install Ely.by PHP-CS-Fixer rules via composer with
+[PHP-CS-Fixer](https://github.com/FriendsOfPHP/PHP-CS-Fixer):
+
+```sh
+composer require --dev friendsofphp/php-cs-fixer ely/php-code-style
+```
+
+Then create file `.php-cs` with following contents:
+
+```php
+<?php
+$finder = \PhpCsFixer\Finder::create()
+    ->in(__DIR__);
+
+return \Ely\CS\Config::create()
+    ->setFinder($finder);
+```
+
+And that's it. You can now find code style violations with following command:
+
+```sh
+vendor/bin/php-cs-fixer --diff --dry-run -v fix 
+```
+
+And then completely fix them all with:
+
+```sh
+vendor/bin/php-cs-fixer fix
+```
+
+### Configuration
+
+You can pass a custom set of rules to the `\Ely\CS\Config::create()` call. For example, it can be used to validate a
+project with PHP 7.0 compatibility:
+
+```php
+<?php
+return \Ely\CS\Config::create([
+    'visibility_required' => ['property', 'method'],
+])->setFinder($finder);
+```
+
+## Code style
+
+Our code style is based primarily on [PSR-2](https://www.php-fig.org/psr/psr-2/), while borrowing some ideas from
+[PSR-12](https://github.com/php-fig/fig-standards/blob/92b198bb/proposed/extended-coding-style-guide.md)
+with some changes.
+
+### Example
+
+This example encompasses some of the rules below as a quick overview:
+
+```php
+<?php
+declare(strict_types=1);
+
+namespace Vendor\Package;
+
+use Vendor\Package\SomeNamespace\ClassA;
+
+class Foo extends Bar implements FooInterface {
+    use SomeTrait;
+
+    private const SAMPLE_1 = 123;
+    private const SAMPLE_2 = 321;
+
+    public $field1;
+
+    public $field2;
+
+    public function sampleFunction(int $a, int $b = null): array {
+        if ($a === $b) {
+            $result = bar();
+        } else {
+            $result = BazClass::bar($this->field1, $this->field2);
+        }
+
+        return $result;
+    }
+    
+    public function setToNull(): self {
+        $this->field1 = null;
+        return $this;
+    }
+
+}
+```
+
+**Key differences:**
+
+* Opening braces for classes MUST be **on the same line**.
+
+* Opening braces for methods MUST be **on the next line**.
+
+**Additional rules:**
+
+* There MUST be one empty line before `return` statement, except when there is only one statement before it.
+  
+  ```php
+  <?php
+  
+  function a() {
+      $a = '123';
+      return $a . ' is a number';
+  }
+
+  function b() {
+      $a = '123';
+      $b = 'is';
+
+      return $a . ' ' . $b . ' a number';
+  }
+  ```
+
+* There MUST be one blank line around class body, but there MUST be **no blank lines** around anonymous class body.
+  
+  ```php
+  <?php
+  class Test {
+  
+      public function method() {
+          $obj = new class extends Foo {
+              public function overriddenMethod() {
+                  // code body
+              }
+          };
+      }
+  
+  }
+  ```
+
+* Visibility MUST be declared for all methods, properties and constants.
+
+* There MUST be one blank line after an each of `if`, `switch`, `for`, `foreach`, `while` and `do-while` bodies.
+  
+  ```php
+  <?php
+  if (true) {
+      // some actions here
+  }
+  
+  echo 'the next statement is here';
+  ```
+
+## Using our fixers
+
+First of all, you must install Ely.by PHP-CS-Fixer package as described in the [installation chapter](#installation).
+After that you can enable our custom fixers with `registerCustomFixers` method:
+
+```php
+<?php
+// Your Finder configuration
+
+return \PhpCsFixer\Config::create()
+    ->registerCustomFixers(new \Ely\CS\Fixers());
+```
+
+And then you'll be able to use our custom rules.
+
+### `Ely/blank_line_around_class_body`
+
+Ensure that a class body contains one blank line after its definition and before its end:
+
+```diff
+--- Original
++++ New
+@@ @@
+  <?php
+  class Test {
++
+      public function func() {
+          $obj = new class extends Foo {
++
+              public $prop;
++
+          }
+      }
++
+  }
+```
+
+**Configuration:**
+
+* `apply_to_anonymous_classes` - should this fixer be applied to anonymous classes? If it is set to `false`, than
+  anonymous classes will be fixed to don't have empty lines around body. **Default**: `false`.
+
+* `blank_lines_count` - adjusts an amount of the blank lines. **Default**: `1`.
+
+### `Ely/blank_line_before_return`
+
+This is extended version of the original `blank_line_before_statement` fixer. It applies only to `return` statements
+and only in cases, when on the current nesting level more than one statements.
+
+```diff
+--- Original

+@@ @@
+ <?php

+ }
+
+ public function bar() {
+     $this->foo();
+     return 'okay';
+ }
+```
+
+### `Ely/line_break_after_statements`
+
+Ensures that there is one blank line above the next statements: `if`, `switch`, `for`, `foreach`, `while`
+and `do-while`.
+
+```diff
+--- Original

+@@ @@
+ <?php

+     if ($number === 3) {
+         echo 'it is three!';
+     }
+ }
++
+ $c = 'next statement';
+```
+
+### `Ely/new_with_braces`
+
+This is the extended version of the original `new_with_braces` fixer. It allows you to remove braces around
+an anonymous class declaration in a case when said class constructor doesn't contain any arguments.
+
+```diff
+--- Original
++++ New
+@@ @@
+ <?php
+-$a = new Foo;
++$a = new Foo();
+-$b = new class() extends Foo {};
++$b = new class extends Foo {};
+```
+
+**Configuration:**
+
+* `remove_for_anonymous_classes` - if its set to `true`, then braces for anonymous classes without constructor
+  arguments will be removed. **Default**: `false`.
