PKC MediaWiki configuration data

The configuration file should have the following entries:

## Database settings
$wgDBtype = "mysql";
$wgDBserver = "database";
$wgDBname = "my_wiki";
$wgDBuser = "wikiuser";
$wgDBpassword = "example";

Note that the value for $wgDBserver is often suggested to be localhost, and in the docker-compose.yml file for PKC, it is set to be database already.

For the purpose of learning how to set up PKC, the administrator is set to be: Administrator user name: admin Password:YOUR PREFERED KEY PHRASE

It is suggested to change the password to a value of your choice. The interface is in the Special:Preferences page.
