Integrate Parse.com with Codeigniter

I am doing a web and I have the data in Parse.com and I need use Codeigniter, but there is a config file in Codeigniter "database.php" that has some parameters like this:

['hostname'] The hostname of your database server.
['username'] The username used to connect to the database
['password'] The password used to connect to the database
['database'] The name of the database you want to connect to
['dbdriver'] The database type.

And I don't know how edit this file.

Thank you.
