+Website Sale Cart Quantity Shop
+=======================================
+
+- **Plus and Minus Buttons**: 
+  - Users can increase or decrease the quantity of a product by clicking the plus (+) or minus (−) buttons next to the quantity input field.
+  - Clicking the plus button increments the quantity by 1.
+  - Clicking the minus button decrements the quantity by 1, with a minimum value of 0.
+
+- **Direct Input**: 
+  - Users can manually enter the desired quantity directly into the input box in the middle of the buttons.
+  - The input field validates and updates the quantity based on user input.
+
+- **Dynamic Updates**:
+  - The quantity input field dynamically updates the cart when the quantity is changed using either the buttons or by direct input.
+  - The system ensures that the quantity displayed is in sync with the quantity available in the cart.
+
+- **Visual Feedback**:
+  - The input field's background color and text color change when the quantity matches the available stock, providing visual feedback to the user.
+
+Usage
+=====
+
+1. **Navigate to the Shop Page**:
+   - Go to your shop or category page in the Odoo eCommerce interface.
+
+2. **Adjust Product Quantity**:
+   - Use the plus (+) button to increase the quantity by 1.
+   - Use the minus (−) button to decrease the quantity by 1, ensuring the quantity does not drop below 0.
+   - Enter a specific quantity directly into the input field to set the desired amount.
+
+3. **Visual Feedback**:
+   - Observe changes in the input field color to reflect the available stock.
+
+Configuration
+=============
+
+No additional configuration is required. The module integrates seamlessly with the existing product quantity functionality on the shop page.
+
