well, and this cloned copy won't need any configuration(i.e: database or something) as when I install PMA for personal usage?
Each copy of phpMyAdmin that’s intended to be used, so the cloned one as well, needs a configuration file.
However, throw a peek into the root folder .gitignore file. You will find that the custom config.inc.php that you need to create is ignored by Git and won’t get added to your commits.
As for the database, if you want to test the local installation, a local mySQL server is best. Provided that your firewall allows outgoing access on port 3306, and that you have a remote mySQL server allowing access from your local phpMyAdmin server IP, you may specify any server you want to, in config.inc.php. It doesn’t necessarily have to be a localhosted mySQL server (which in turn speeds up any communication).
