 # Plugin Reference Cleaner
-
-A WordPress plugin that adds a "Remove Reference" button to plugin deactivation error notices, allowing users to clean up invalid plugin entries in the database.
+Author: Marcus Quinn
+Author URI: https://www.wpallstars.com
+Version: 1.2.3
+License: GPL-2.0+
 
 ## Description
 
+Have you ever deleted a plugin some other way than through the /wp-admin/plugins.php page? If so, you've probably been stuck with this annoying notification that can't be cleared:
+
+"The plugin folder-name/file-name.php has been deactivated due to an error: Plugin file does not exist."
+
+This small WordPress utility plugin adds a "Remove Reference" button to these plugin deactivation error notices, allowing you to clean up the invalid plugin entries in the database.
+
 When WordPress detects a plugin file that no longer exists but is still referenced in the database as active, it displays an error notice. This plugin enhances those notices with a button that allows you to safely remove the invalid reference with a single click.
 
-**Note:** This plugin only needs to be installed and active if you have an error notification showing like this:
+You can find these with `SELECT * FROM wp_options WHERE option_name = 'active_plugins';` — but the cleanup involves removing the rogue entry, and renumbering all others. This plugin can simply do that for you at the click of a button added to that WP standard notification.
+
+It's probably something that should be added to WP core. If anyone from the core team wants to adopt this solution, it's GPL, so feel free.
+
+Note: This plugin only needs to be installed and active if you have an error notification showing at /wp-admin/plugins.php, like this:
 "The plugin folder-name/file-name.php has been deactivated due to an error: Plugin file does not exist."
 
+If you don't have this notification perpetually showing on your /wp-admin/plugins.php page, then you don't need this, but you might like to save or bookmark it for if ever you do.
