 You can now use `./vendor/bin/ecs` to list all violations of the defined standard and `./vendor/bin/ecs --fix` to
 automatically fix them.
 
-#### PHP Codesniffer
-
-The PHPCodesniffer is sort of a combination of the previous tools, it checks for a defined codingstyle and some extra
-rules that are not just stylechanges but instead enforces extra rules in if-statements, exception handling etc.
-
-it provides the `phpcs` command to check for violations and the `phpcbf` command to actually fix most of the violations.
-
-Without configuration the tool tries to apply the PSR12 standard just like the php-cs-fixer, but as you might have
-guessed we are adding some extra rules.
-
-Lets install the ruleset with composer
-```shell
-composer require --dev mnapoli/hard-mode
-```
-
-and add a configuration file to actually use it `.phpcs.xml.dist`
-```xml
-<?xml version="1.0"?>
-<ruleset>
-    <arg name="basepath" value="."/>
-
-    <file>src</file>
-
-    <rule ref="HardMode"/>
-</ruleset>
-```
-
-running `./vendor/bin/phpcs` now checks our src directory for violations and gives us a detailed list about the findings.
