Hi Willian,
You don't need to run phpcs yourself, we have a continuous integration server that runs it every 10 minutes provided that there are new commits on master. Just select "checkstyle warnings" in the left menu on this page: http://ci.phpmyadmin.net/job/phpMyAdmin-continuous/
Bye, Rouslan

I would like to help in this task. How should I run phpcs to get these warnings? Thank you very much.
