+=======================================================
+Website Sale Free Qty Virtual Available
+=======================================================
+
+Overview
+========
+
+The **Website Sale Free Qty Virtual Available** module replaces the usage of `free_qty` with `virtual_available` to determine if stock is available or not in the context of online sales. This adjustment ensures that only the available quantity (considering reserved stock) is used to check stock availability.
+
+Features
+========
+
+- **Stock Availability Based on Virtual Available**:
+  - The module uses the `virtual_available` field instead of `free_qty` to determine if a product is available for sale, ensuring a more accurate representation of stock levels.
+
+- **Customization**:
+  - Modifies the product availability template to check stock availability using `virtual_available` when determining if the product is out of stock.
+
+- **Updated Variant Controller**:
+  - The module extends the variant controller to include the `virtual_available` value for a product, ensuring accurate stock information is provided when querying product combinations.
+
+Usage
+=====
+
+1. **Install the Module**:
+   - Install the **Website Sale Free Qty Virtual Available** module from the Apps menu.
+
+2. **Product Availability Check**:
+   - After installation, the stock availability check on the website will be based on the `virtual_available` field, which accounts for both real stock and reserved quantities.
+
+3. **Combination Info**:
+   - When querying product combinations, the updated `virtual_available` value will be included in the response, providing accurate stock information for each variant.
+
+Configuration
+=============
+
+No additional configuration is required. The module will automatically replace the use of `free_qty` with `virtual_available` for stock availability checks.
+
+Testing
+=======
+
+1. Test by adding a product to the website and verifying that the stock status is based on `virtual_available`.
+2. Confirm that when querying product combinations, the `virtual_available` field is correctly included in the response.
