Manual:Configuring MediaWiki
Basic configuration
When you first install MediaWiki, you should run the supplied configuration script via your web browser. This will perform the basic configuration required to get the wiki up and running. See Manual:Config script for full details running the script.
Further configuration
Once the wiki has been installed and configured using the above configuration script, any further customizations need to be made by configuring LocalSettings.php.
For help with more advanced technical configuration, see Manual:System administration and Manual:Administrators.
