 # git-hook-handler
 
-
+## Usage
 Just create a `git-hooks.yml` file in your projects base directory, and fill it with an array of commands you want to run:
 
-```yml
+```yaml
+# git-hook.yml
+config:
+    commit-on-error : true # or false
 pre-commit:
-    - bldr run ci
-    - phpunit
+    # Simple command
     - bin/phpcs
+    # or more complex command
+    - phpunit:
+        description : 'Run PHPUnit'
+        command : phpunit
+        exitcode : 0
+    phpcs-fixer:
+        description : 'Checking PHP Syntax with PHP-CS-FIXER'
+        exitcode : 0
+        command : >4
+            COMMIT_RANGE='HEAD~..HEAD' &&
+            CHANGED_FILES=$(git diff --name-only --diff-filter=ACMRTUXB "${COMMIT_RANGE}") &&
+            if ! echo "${CHANGED_FILES}" | grep -qE "^(\\.php_cs(\\.dist)?|composer\\.lock)$"; then IFS=$'\n' EXTRA_ARGS=('--path-mode=intersection' '--' ${CHANGED_FILES[@]}); fi
+            && ./vendor/bin/php-cs-fixer fix --config=.php_cs.dist -v --dry-run --using-cache=no "${EXTRA_ARGS[@]}"
+
 post-merge:
-    - bldr run compileAssets
+    command_name:
+        description : 'lorem ipsum'
+        command : 'mycommand'
+        exitcode : 0
 ```
 
 and then place the following in your composer.json, then run `composer install` or `composer update`
 
 ```json
+# composer.json
     "scripts": {
         "pre-update-cmd":  "Aequasi\\HookHandler\\HookScript::install",
         "pre-install-cmd": "Aequasi\\HookHandler\\HookScript::install"
