Businness

Your plugin’s URL will be populated based on the value of Plugin Name in your main plugin file (the one with the plugin headers). If you set yours as Plugin Name: Boaty McBoatface then your URL will be https://wordpress.org/plugins/boaty-mcboatface and your slug will be boaty-mcboatface for example. If there is an existing plugin with your name, then you will be boaty-mcboatface-2 and so on. It behaves exactly like WordPress post names.
