1. Install the module via composer:
   • Console run:

       composer require --dev streamcommon/coding-standard

   • Or add into your composer.json:

       "require-dev": {
           "streamcommon/coding-standard": "*"
       }

2. Add composer scripts into your composer.json:

            "cs-check": "phpcs",
            "cs-fix": "phpcbf"
        }

3. Create file phpcs.xml:

       <?xml version="1.0"?>
           <ruleset name="StreamCommon Team Coding Standard">
           <rule ref="./vendor/streamcommon/coding-standard/ruleset.xml"/>
           <file>bin</file>
           <file>config</file>
           <file>lib</file>
           <file>src</file>
           <file>test</file>
       </ruleset>
