There aren't particular dependencies, just note that the backend follows the .htaccess rules and DB schema that you can find in the utility folder.
Edit the database.php file that is in the config folder in order to connect to your database.
Edit the clientSecret and clientID and the URL to your Auth Server in the index.php of the Authentication folder in order to implement OAuth Authentication with the Bearer Token.
