These files complete the core functionality of the plugin. The settings.php file provides a comprehensive settings interface in the WordPress admin area, allowing administrators to configure all aspects of the defensive driving registration system, including:

General settings (company information)
Form settings (customizable form fields, court options, violation codes, course types)
Payment settings (Stripe and PayPal integration)
Email settings (notification templates and settings)
The main plugin file initializes the plugin and loads all required dependencies, while the installation class sets up the database table and default options when the plugin is activated.
