-  Magento_ConfigurableProduct module introduces new product type in the Magento application called Configurable Product.
+  The Magento_ConfigurableProduct module introduces new product type in the Magento application called Configurable Product.
   This module is designed to extend existing functionality of Magento_Catalog module by adding new product type.
 
   Configurable Products let the customers select the variant they desire by choosing options.
   For example, store owner sells t-shirts in two colors and three sizes.
+
+  ## Structure
+
+  `ConfigurableProduct/` - the directory that declares ConfigurableProduct metadata used by the module.
+
+  For information about a typical file structure of a module in Magento 2, see [Module file structure](https://devdocs.magento.com/guides/v2.4/extension-dev-guide/build/module-file-structure.html#module-file-structure).
+
+  ## Extensibility
+
+  Extension developers can interact with the Magento_ConfigurableProduct module. For more information about the Magento extension mechanism, see [Magento plug-ins](https://devdocs.magento.com/guides/v2.4/extension-dev-guide/plugins.html).
+
+  [The Magento dependency injection mechanism](https://devdocs.magento.com/guides/v2.4/extension-dev-guide/depend-inj.html) enables you to override the functionality of the Magento_ConfigurableProduct module.
+
+  ## Additional information
+
+  ### Configurable variables through the theme view.xml
+
+  Modify the value of the `gallery_switch_strategy` variable in the theme view.xml file to configure how gallery images should be updated when a user switches between product configurations.
+
+  Learn how to [configure variables](https://devdocs.magento.com/guides/v2.4/frontend-dev-guide/themes/theme-images.html#view_xml_vars) in the view.xml file.
+
+  There are two available values for the `gallery_switch_strategy` variable:
+
+  Value | Description
+  --- | ---
+  `replace` | In replace mode, images of the parent configurable product will be replaced by the simple product images upon a configuration change
+  `prepend` | In prepend mode, the simple product images will be added in front of the parent configurable product upon a configuration change
+
+  If the `gallery_switch_strategy` variable is not defined, the default value `replace` will be used.
+
+  For example, adding these lines of code to the theme view.xml file will set the gallery behavior to `replace` mode. 
+
+  ```xml
+  <vars module="Magento_ConfigurableProduct">
+      <var name="gallery_switch_strategy">replace</var>
+  </vars>
+  ```
