 # phpMyAdmin Coding Standard
 
-phpMyAdmin Coding Standard for PHP CodeSniffer.
+phpMyAdmin Coding Standard is a set of [PHP_CodeSniffer](https://github.com/squizlabs/PHP_CodeSniffer) rules and is based on the [Doctrine Coding Standard](https://github.com/doctrine/coding-standard).
 
-## Installation & Usage
+## Installation
 
-### Manual installation
-Before starting using our coding standard install [PHP_CodeSniffer](https://github.com/squizlabs/PHP_CodeSniffer).
-
-Clone or download this repo somewhere on your computer or install it with [Composer](https://getcomposer.org/).
-To do so, add the dependency to your `composer.json` file by running `composer require --dev phpmyadmin/coding-standard`.
-
-### Automatic installation with Composer
-Much easier, however, is to use Composer to install the necessary files automatically.
-Using the development version of phpMyAdmin from git requires using Composer, so the dependencies are already set
-in `composer.json` using the 'require-dev' section. Depending on your system, this will either be installed
-automatically unless you use `--no-dev` option or composer must be run with `--dev`. Regardless of your composer
-version, using `--dev` will always install the 'require-dev' dependencies, so we recomment using Composer with that
-option.
-
-### Final configuration
-Add the standards directory to PHP_CodeSniffer installed paths. You probably have to use the full/absolute path
-rather than a relative one, otherwise you will get an "Unexpected Value Exception":
-
-```sh
-$ phpcs --config-set installed_paths /var/www/html/phpmyadmin/vendor/phpmyadmin/coding-standard
-```
-
-You can verify whether the standard can be found:
-
-```sh
-$ phpcs -i
-The installed coding standards are MySource, PSR1, PHPCS, Zend, Squiz, PEAR, PSR2 and PhpMyAdmin
 ```
-
-Run CodeSniffer:
-
-```sh
-$ phpcs --standard=PhpMyAdmin /path/to/code
+composer require --dev phpmyadmin/coding-standard
 ```
 
-You can optionally make PhpMyAdmin the default for all invocations of phpcs, then you don't need to
-manually specify it each time on the command line:
+## Usage
 
-```sh
-$ phpcs --config-set default_standard PhpMyAdmin
 ```
-
-## Using
-
-PhpMyAdmin has its tuned coding style checks, such as missing `@author`,
-`@copyright`, `@link` or other tags. Let's take a look at an example, checked with PhpMyAdmin:
-
-```sh
-$ phpcs --standard=PhpMyAdmin /path/to/code/myfile.php
-123 | WARNING | Line exceeds 85 characters; contains 139 characters
-184 | ERROR   | Line indented incorrectly; expected at least 20 spaces, found
-    |         | 16
-272 | ERROR   | Closing parenthesis of a multi-line IF statement must be on a
-    |         | new line
-272 | ERROR   | Multi-line IF statement not indented correctly; expected 12
-    |         | spaces but found 9
+vendor/bin/phpcs --standard=PhpMyAdmin /path/to/code
 ```
