The wp-config.php file is the most important file in WordPress as it handles database authentication and security settings. It can be used to configure environments, enable debugging locally, disable changes on production, force SSL, and move folders. More advanced uses include changing post revisions, enabling WordPress Multisite, increasing PHP memory limits, and putting Jetpack into debug mode. The WordPress codex provides more information on editing wp-config.php.
