# Constraints

The plugin has a WebSub posthook that enables MFN to inject news items when they are published. This means that the WP application must be initiated from within the plugin.

This puts some constraints on the folder structure of the Wordpress instance. In short, the plugin must be able to find `wp-config.php` to bootstrap the necessary parts. The plugin does this by traversing parent directories of the plugin, at a maximum height of 3. This should work for both Bedrock and standard installations of Wordpress.
