 # Mollie PHP Coding Standards
-
 Contains PHP coding standards like rules for PHP-CS-Fixer that serves for purpose of standardization.
+
+## Usage
+This package makes use of PHP-CS-Fixer.
+
+### Already familiar with PHP-CS-Fixer
+
+This package provides default rules to be used with PHP-CS-Fixer.
+
+You can find them in `Mollie\PhpCodingStandards\PhpCsFixer\Rules` which has methods specific to php version,
+which you can directly use in the `->setRules()` part of your config. For example, assuming PHP version 7.3:
+
+```php
+use Mollie\PhpCodingStandards\PhpCsFixer\Rules;
+
+$config->setRules(Rules::getForPhp73());
+``` 
+
+### New to PHP-CS-Fixer
+
+Place a file named `.php_cs.dist` that has following content in your project's root directory.
+
+```php
+use Mollie\PhpCodingStandards\PhpCsFixer\Rules;
+use PhpCsFixer\Config;
+use PhpCsFixer\Finder;
+
+$finder = Finder::create()
+    ->name('.php_cs.dist') // Fix this file as well
+    ->in(__DIR__);
+
+return Config::create()
+    ->setFinder($finder)
+    ->setRiskyAllowed(true)
+    // use specific rules for your php version e.g.: getForPhp71, getForPhp72, getForPhp73
+    ->setRules(Rules::getForPhp71());
+```
+
+### Manual Triggering
+Run following command in your project directory, that will run fixer for every `.php` file.
+```bash
+vendor/bin/php-cs-fixer fix
+```
+
+### Use via PhpStorm file watcher
+Please follow [official PhpStorm documentation](https://www.jetbrains.com/help/phpstorm/using-php-cs-fixer.html#f21a70ca)
+
+### Use via pre-commit git hook
+Place a file with the content of the following bash script into `.git/hooks` directory called pre-commit and make it executable 
+you can find more details about git hooks on [official git manual](https://git-scm.com/book/en/v2/Customizing-Git-Git-Hooks). 
+
+```bash
+#!/usr/bin/env bash
+
+EXCLUDE_DIRECTORIES_REGEX='^(directory_one/(sub_directory_one|sub_directory_two)|directory_two)/.*'
+git diff --diff-filter=ACMRTUXB --name-only --staged | grep -E '\.php(_cs\.dist)?$' | grep -vE $EXCLUDE_DIRECTORIES_REGEX |  while read FILE; do
+    STATUS="$(git status --porcelain ${FILE} | cut -c 1-2)"
+    vendor/bin/php-cs-fixer fix --using-cache=no --quiet --dry-run ${FILE}
+
+    # Not 0 means php-cs-fixer either errored or wanted to make changes
+    if [ $? != 0 ]
+    then
+        # MM = staged & non-staged modification in same file
+        if [ ${STATUS} = "MM" ]
+        then
+            echo -e "\033[31m┌────────────────────────────────────────────────────────────────────────────────┐"
+            echo -e "│ Failure:\033[39m Codestyle violation(s) in file with both staged and unstaged changes. \033[31m│"
+            echo -e "├────────────────────────────────────────────────────────────────────────────────┘"
+            echo -e "└\033[33m File:\033[39m    $FILE"
+            exit 1
+        fi
+
+        vendor/bin/php-cs-fixer fix --using-cache=no --quiet ${FILE}
+        git add ${FILE}
+    fi
