+Purchase Add Extra Line Extension
+=================================
+
+This module introduces an automated process for adding extra lines
+(e.g., service fees, handling charges, or supplementary products) to
+Purchase Orders in Odoo. It's designed to help procurement teams
+consistently apply additional costs or items based on the primary
+products being purchased.
+
+Key Features
+============
+
+1. **Configurable Extra Products**:
+
+   - Allows users to define an **Extra Product** directly on the product
+     template.
+   - Enables automated adding of this extra line whenever the primary
+     product is added to a Purchase Order.
+
+2. **Flexible Pricing Logic**:
+
+   - The unit price for the extra line can be computed as a
+     **percentage** of the primary product's price.
+   - If the percentage is set to zero, the system uses the standard
+     **List Price** of the extra product.
+
+3. **Procurement Efficiency**:
+
+   - Reduces manual entry errors and ensures that all mandatory
+     supplementary costs or items are included in every relevant
+     Purchase Order.
+
+Usage
+=====
+
+1. Go to **Purchase > Products > Products**.
+2. Open a product and locate the **Extra Line Configuration** (typically
+   in the Purchase or a dedicated tab).
+3. Select the **Extra Product** you want to associate and set the
+   **Percentage** (if applicable).
+4. Create a new **Purchase Order** and add the primary product to the
+   order lines.
+5. The system will automatically add the extra product as a separate
+   line with the pre-calculated price.
