+# Website Sale Cart Line Subtotal
+
+## Description
+
+This module adds a "Subtotal" column to the shopping cart lines that displays the total amount for each line (quantity × unit price).
+
+### Problem
+
+By default, the Odoo website shopping cart shows:
+- Product quantity
+- Unit price
+
+But it doesn't show the line total (quantity × price), which can be confusing for customers when they want to quickly see how much each line is costing them.
+
+### Solution
+
+This module adds a new "Subtotal" column that shows:
+- `price_subtotal` (without taxes) for users with tax-excluded view
+- `price_total` (with taxes) for users with tax-included view
+
+The subtotal column is inserted between the "Price" and action columns in the cart.
+
+## Installation
+
+1. Install the module from the Apps menu
+2. No additional configuration is required
+
+## Usage
+
+After installation:
+1. Add products to your cart
+2. Go to the shopping cart page
+3. You will see a new "Subtotal" column showing the line total for each product
+
+The subtotal respects your tax display configuration (with or without taxes).
