+# QDR - Studiou WC Order Print Statuses
+
+## Description
+
+QDR - Studiou WC Order Print Statuses is a WordPress plugin that extends WooCommerce functionality to manage print orders sent to third-party providers. It adds custom order statuses, bulk actions, and status change timestamps specific to the printing process.
+
+## Features
+
+- Custom order statuses: "Prepare to Printing" and "In Printing"
+- Bulk actions for managing print orders
+- Custom order fields for tracking print-related information
+- Custom columns in the orders list for quick view of print statuses
+- Import functionality for InPrint and Delivered protocols
+- Search orders by external reference order number
+
+## Installation
+
+1. Upload the `studiou-wc-ord-print-statuses` folder to the `/wp-content/plugins/` directory
+2. Activate the plugin through the 'Plugins' menu in WordPress
+3. Ensure WooCommerce is installed and activated
+
+## Usage
+
+### Custom Order Statuses
+
+The plugin adds two new order statuses:
+
+- Prepare to Printing
+- In Printing
+
+These statuses appear in the order status dropdown and can be used to track the progress of print orders.
+
+### Custom Order Fields
+
+In the order edit page, you'll find a new section called "Print Information" with the following fields:
+
+- Prepare To Print Date
+- In Print Date
+- External Order Number
+- External Order Delivered
+
+### Bulk Actions
+
+New bulk actions are available in the orders list:
+
+- Prepare to Printing Export: Exports selected orders and changes their status to "Prepare to Printing"
+- Set Status to Prepare to Printing
+- Set Status to In Printing
+
+### Custom Columns
+
+The orders list now includes new columns:
+
+- To Print Date
+- In Print Date
+- External Order Number
+
+### Import Functionality
+
+Two import buttons are added to the orders page:
+
+- Import InPrint Protocol: Updates order status to "In Printing" and sets related metadata
+- Import Delivered Protocol: Updates order status to "Completed" and sets delivery date
+
+## Requirements
+
+- WordPress 5.0 or higher
+- WooCommerce 3.0 or higher
