+## Running Coding Standards Checks
+
+This component uses [php-cs-fixer](http://cs.sensiolabs.org/) for coding
+standards checks, and provides configuration for our selected checks.
+`php-cs-fixer` is installed by default via Composer.
+
+To run checks only:
+
+```console
+$ ./vendor/bin/php-cs-fixer fix . -v --diff --dry-run --config-file=.php_cs
+```
+
+To have `php-cs-fixer` attempt to fix problems for you, omit the `--dry-run`
+flag:
+
+```console
+$ ./vendor/bin/php-cs-fixer fix . -v --diff --config-file=.php_cs
+```
+
+If you allow php-cs-fixer to fix CS issues, please re-run the tests to ensure
+they pass, and make sure you add and commit the changes after verification.
