+### Why use the online generator?
+
+Our goal is to provide you with a drop-in script that complies as closely to WordPress coding standards and best practices, as possible. With this in mind, the online generator will:
+
+* Prefix all PHP class names to match your theme or plugin name.
+* Name all class files to correctly correspond to the name of those PHP classes.
+* Insert your unique namespacing key for anything submitted to the database.
+* Insert the localization text domain that matches your theme or plugin.
+* If the "plugin" usage type is selected, `add_theme_page()` will be substituted for `add_submenu_page()` (not allowed in themes).
+* Give you an example code snippet to get started, which is customized to your project.
