+ * Plugin Name: Monorepo Query Monitor Helper
+ * Description: Helps with debugging by providing better labels for Query Monitor.
+ * Version: 1.0
+ * Author: Automattic
+ * Author URI: https://automattic.com/
+ * Text Domain: jetpack
+ *
+ * @package automattic/jetpack
+ *
+ *
+ * This file contains hooks for Query Monitor, which is a debugging tool for WordPress.
+ * It allows you to see all the queries that are being run on your development environment.
+ * It defines three filter hooks that modify how Query Monitor categorizes and displays components in its output:
+ *
+ *  * qm/component_type/unknown:
+ *    This filter categorizes files as either 'plugin' or 'other' based on their file path.
+ *	  files containing 'projects/plugins/jetpack' are marked as 'plugin', while those with 'projects/packages' are marked as 'other'.
+ *  * qm/component_name/plugin:
+ * 	  This filter renames components identified as plugins.
+ *    If the file path contains 'projects/plugins/jetpack', it's labeled as 'Plugin: jetpack'.
+ *  * qm/component_name/other:
+ *    This filter renames components identified as 'other'.
+ *    For files in the 'projects/packages/' directory, it extracts the package name from the file path
+ *   and labels it as 'Package: connection'.
+ *
+ * @package automattic/jetpack
